My boyfriend and I had unprotected sex 3 days before my period was supposed to come. We had sex on Oct 27th and my period was supposed to come on the 29-30th. It is now the 1st of November and my period has not come. Is there a possibility I could be pregnant?

Yeah... and it's a good one.

Yes, but it would be too early to test. At this point you wouldn't even officially be pregnant (study reproduction and how it works and you'll understand what I mean).

The fact is, unless you're tracking ovulation (not with an app on your phone) and know exactly when you ovulate, pregnancy is possible any time you have sex. Women have gotten pregnant while on their period. It happens.

Wait at least 2 more weeks. If you haven't gotten your period than test using first morning urine. If it's negative than wait until your next period is due. If you miss it than test again or see a doctor for a more accurate blood test.

If you're not ready to be a mom, than don't have sex, that's the only method of birth control that's 100% effective.

Sometimes the female body does some funky things when it involves periods and pregnancies. In a week take a pregnancy test or see your feminine doctor to get more information.

I'm curious. The OP (original poster) had sex 4 days ago. A week from, with or without a period, she'd be at the very very very early stages of pregnancy. The majority of women won't get an accurate result, either at home or at the doctors, at this stage in pregnancy. What information will her "feminine doctor" be able to give her at 11 days after sex?
