I’m scared, me and my friend I’ve been talking to, March makes 5 years, have been having unprotected sex since I’ve got to town which was on the 5th.. my cycle was suppose to come on last Sunday.. I took a pregnancy test the 2nd day I was late but it was negative, im stressed and worried, I don’t know what to do next.. do I wait it out to see if it comes on or just go to a doctor?
