"hi, I was wanting to know if I had sex on may 8th and my cycle came on on may 16th but has came yet for June could I pregnant or what is going on ? Please help

Sure you could be pregnant. You could also have a huge tumor. Or you could have a hormone imbalance. Or you could just be late. The point I'm making here is that nobody online could tell you. If you had sex, there is always the possibility of pregnancy. Take a pregnancy test.
