Ok the story is me and my boyfriend had unprotected sex only two days after my period ended and i'm not really sure if he ejaculated in me or not. Anyway for the past two weeks i've felt really nauseous (no vomitting), I've been cramping much like if i were on my period and I've kept a temperature of 99-99.3 which i read that was a sign of pregnancy, I've also had mild headaches, been constipated, I'm constantly tired, my breast are very tender and my period is now 4 days late. When I started having these syptoms i got a little stressed though because i don't really want a kid so my question is am i pregnant or am i just stressed? Can someone please help me??
