Why is my left breast painful and bigger than the right?

Hello,

Welcome to icliniq.com.

I understand your concern.

It is completely natural to feel worried about unequal breast pain and the possibility of pregnancy after unprotected sexual intercourse.

Just before menstruation (period), the level of progesterone begins to drop, and other hormonal changes occur. These changes can cause breast heaviness and pain, which are normal findings and not usually a cause for concern. Both breasts are not identical in size (this is normal for most women), so their response to hormonal changes may differ. This is why one breast may feel fuller, more swollen, or more tender than the other. It is normal. So, the possible cause is premenstrual syndrome (PMS).

If the pain is very uncomfortable, you may take Paracetamol (Acetaminophen)or any other appropriate pain reliever available to you. The discomfort usually settles once the period starts.

Regarding pregnancy risk, you were on the twenty-first day of your cycle when you had sexual intercourse, which is typically outside the fertile window. Therefore, the chance of pregnancy is extremely low.

There is no cause for concern at this time. The breast pain is most likely a normal response to hormonal changes that occur before the period starts and is not related to pregnancy.

Hello,

Welcome back to icliniq.com.

I understand your concern.

It is most likely related to premenstrual changes, and you are not pregnant. Before menstruation, there is congestion of the pelvic vessels (blood supply around the uterus and ovaries). This can cause a feeling of heaviness and a sensation of firmness in the breast tissue. It may be more noticeable on one side than the other. So, you are not pregnant.
