Hi, I had unprotected sex on the 13th of March and my period came on March 16th and it was normal but then I had unprotected sex again on the 29th March and my period came two weeks later but was five days early and lasted 4 days.. could I be pregnant?

Lately I've been experiencing breast pain, tirdness a lot, sick in the stomach, gives me these weird feelings in the abdominals, headaches, back pain, peeing a lot and have a strong urine smell but not too strong and cravings a lot. I have been eating so much that I always feel hungry and then my stomach hurts. Please help! Thank you!
