Ouch! My Breasts!

An early sign of pregnancy, during the first trimester, are swollen or sore breasts. This can begin as early as a week after conception, often before a woman ever misses her period. The breasts might become larger, tender, and ache when they are touched. But what causes this tenderness?

A woman’s breasts are made up of fat, tissue, blood, and milk glands and their sole purpose is for breastfeeding. It is just a coincidence that the men seem to like women’s breasts as much as the babies do.

When a woman gets pregnant her breasts immediately start preparing to feed that baby nine months down the road. Extra blood begins to run through them and the milk glands grow, causing the swelling and pain that a woman might feel. A woman’s breasts will continue to grow throughout pregnancy, although the tenderness should fade after the first trimester. It is normal for a woman’s breasts to be 2-3 cup sizes bigger by the time her baby comes and she begins nursing.

Swollen and sore breasts do not necessarily mean that a woman is pregnant. Many women experience some swelling and tenderness in their breasts every month right before their period comes, or even at ovulation. Sore breasts can also be caused by a hormonal imbalance or starting, stopping, or changing birth control pills midway through a cycle. When in doubt, be sure to call your doctor.

I had sex the day of my last period 7/2, everyday up to my ovulation date of 7/11. this week ive off and on had sore breast, & experienced off and on cramping. I have 6 more days until my next period, I took a test 6 days before my period (I didn’t think it would make a huge difference) it came out negative is it possible that I am pregnant but my HCG level isn’t high enough to detect it??

I have a question, i had sex on the last day of my period. We used a condom but 3 days after i started having tender breast and its been 3 weeks already and i still have tender breast. I dont have fatigue or anything else tho i did notice that my nipples are really sore and got slightly bigger. Could i be pregnant? FYI, I’m regular and my breast always hurt 1 week before my period and then they stop hurting once i get my period. Anyone, please advice or share what you think about this.

I have a unusual experience I was given provera to jump start my period but 3&4 days after taking them I had a positive ovulation test. But obviously implantation wouldn’t happen until a week after my last pill and I just started my period yestersy. I’m 8 dpo today. And my breast are extremely sensitive and sore and are getting worse everyday. Could I still be pregnant even tho I’m bleeding? I sound like a complete idiot but my breast are extremely sore and swollen! HELP!

I had a tubal ligation a year and a half ago. Starting in June til now I have had my periods but have only been 2-3 days and very light. My boobs are sore as hell and yesterday noticed I’m lactating and my stomach is hard as a rock. I’m also nauseated and very irritable. I thought having my tubes tied was like 100% chance of no more kids but now don’t know. I took an at home test that came back negative. But could I still be pregnant? Of not what else could explain these symptoms?

I had stopped taking the contraceptive pill about a week and a half before having unprotected sex last week tuesday. That same tuesday after intercourse I started a new pack. Its been a week since and I have been having slight cramping morning and afternoons and my breasts are sore and swollen. I took a pregnancy test yesterday morning but it came up negative. Could it just be that its symptoms from starting the pill without having a period inbetween when I stopped the pill? Or could it be possible that I am. Pregnant? Really need asvice asap!

OMG, besides breast soreness (It’s almost unbearable) and cravings, I really don’t feel pregnant though my PCM confirmed it and I had two postive pregnancy tests. I’m about 8-9 weeks along, but my morning sickness has mysteriously disappeared. this is my second pregnancy. I was sick 24/7 with my first one. I can barely wear clothes over my breasts coz of the sensitivity. I think that’s my biggest problem. Any advice?

Hi, I have a question. About 2 -4 weeks before my period started, my boyfriend and I had unprotected sex. I had my period as usual, but it was weird. Usually I have a very heavy period that lasts for a week, but last month it only lasted for 4 days, and wasn’t as heavy. Now, 2 weeks after my period ended, my breasts are really sore and feel “full.” I can’t really explain it. They basically feel like two bowling balls just hanging there when I take my bra off, and my nipples hurt A LOT. Even when they… Read more »

To all the women that don’t know if they are pregnant or not. There are very little signs that you can have and still be pregnant. I am 29 yrs old and pregnant with my 5th child. When I got pregnant with my oldest daughter I had no signs of pregnancy at all. I still had my period, didn’t gain weight or any of that til I hit 6 months. When I hit 6 months with her I was like a blimp. I showed big time. before that I didnt show at all. But I still had my period throughout… Read more »

Hello all, yes it is possible to be pregnant and test negative. I have 3 sons and when I was pregnant with my 2nd son my period hadn’t showed itself for 3+ months so here I am sitting at the doctors office having a debate with a nurse who was ready to put money on the fact that she just knew I wasnt pregnant due to her having just gaven me a urine pt. She had a prescription for hormone pills in her hand because “that was all I needed to jumpstart my period”. I told her I know my… Read more »

i there – thank you in advance for your insight. My boyfriend and I have a question regarding potential pregnancy. Here are the details: I my period stopped – became dormant – for a full two years up until 6 months ago. My doctor told me that there was about a %98 percent chance of INFERTILITY for the next 3 – 4 years. This being said, my boyfriend and I have been using the withdrawal method, as I believed that the chances of pregnancy were slim to none. I had my period the week of February 14th. This was approximately… Read more »

My husband and I are ttc and we had unprotected sex on 11/01/11. Within a few days I though I started to get mild cramps and tender breasts sometimes slight dizziness and a light head in the mornings. I then started my period on 20/01/11 (5 days early). Usually I have severe cramps before I come on, only this time I noticed a pink/red show before I had any severe cramping. I have heard about implantation bleeding however this is quite heavy. The cramps only lasted a few hours once they started but they have since stopped. Today I have… Read more »

Hi everyone… I just wanted to make a comment to all the people online here asking if whether they could be pregnant or not. The only sure way to really know is to go see your doctor and have tests done. Pregnancy tests do normally work most of the time, but they do sometimes backfire. I was having major breast pain just prior to my cycle due and took a test…came up negative…then i started what I cycle..but it was too light and kept going for approx 2 weeks. I then again tried another test…again negative. I thought I… Read more »
