If my period was suppose to come on the 8th of June and I had unprotected sex on the 9th but my period didn't come until the 16. I had a period in July but it came later on the 19 and I didn't have a period in August. Could I be pregnant?

YES. You had sex and you could be pregnant. Take a home pregnancy test with first morning urine.

Any time you have sex, even if you use protection, pregnancy is possible.

Are you pregnant? It's possible. Can we tell you? No. We don't have your urine or your blood, and we'd need those in order to tell you if you're pregnant or not. You do have both of those things at your disposal, so it's up to you to take a pregnancy test.
