I had unprotected sex 2 weeks ago, whilst I was on my Period but it was at the end of it and I've been having stretching cramps in my stomach a little and been bloated all the time and my stomach looks slight curved and also I have seen suffering from acne on my chin and around my mouth. also I have been going to the toilet frequently and feeling tired a lot, I haven't done a test yet but can anyone suggest what I should do because I don't know weather I could be pregnant or not
