I have 28 cycle. April 5 is my1st day of menstruation.I and my boyfriend had unprotected sex on day 8 and 14. Is their any chance I could get pregnant?

Yeah.. a good one... apparently you are trying to get pregnant. However its way too soon to know if you've been successful until you are at least two weeks late for your period.

Yes you could be pregnant but you have to wait and find out. That's how sex works.

Any time there is penile insertion there is the chance of pregnancy. You can minimize the chances but not eliminate them. The actions you have taken have worked to increasing your chances not limiting them.

So now you have to wait until your next period is due and see if it comes. If you are late by a week or more you can start taking tests.
