My last period was a week ago. My nipples are usually sore a week before my period. Right now they are sore and it's only been a week prior to my last period. I have A very regular period and have not missed. I did have unprotected sex. Could I be pregnant?

My boobs have been sore for the past two weeks. I have to pee more. I'm tired all the time. I have had unprotected sex. I have been having mood swings a lot lately. I did however take a pregnancy test and it was negative but I haven't missed a period yet.. Could I be pregnant?

Any woman who has unprotected sex (or even protected sex) can get pregnant. Symptoms don't predict much, really. Only taking tests a few days apart will tell you for sure.

Excited perhaps, since I will assume you are trying to get pregnant, since you did not use any protection at all.

It is far to early for a pregnancy test. You will have to wait until time for your period, wait at least one week after when your period should have ended ( not started) and try the pregnancy test then using the first urine of the morning.

These are of course signs, but it is far to early to tell.
