My period came last Friday and my breast seem to be getting bigger for no reason can I be pregnant. I don't feel pregnant

If you had sex, yes you could be pregnant.

Have you taken a HPT yet, or had a doctor administrated test performed?

If your period came on time, you are likely not pregnant. Some people will experience some slight breast enlargement during the time of their period due to the shift in hormones.

See what happens when you would have your next period. If it doesn't show, try a pregnancy test.

If you had a regular period, normally you are not pregnant. There are many reasons for breasts to feel or even be bigger.

If you want you can try a pregnancy test, or wait till next month and see if you miss that period.
