I had my period feb 8-12 and took a plan b on feb 02 and feb 18. I then had my period on feb 24-28. I haven't had my period since. I was suppose to get my period like the 24 according to my period tracker and I have had unprotected sex 3 times but he never came inside me. I have been really stressed as it is and been working out more than usua and idk if that's a reason it can be late or should I be worried. I keep thinking about it I just want it to come already. Any help?
