I had unprotected sex in the beginning of Nov. while I was ovulating and we did the pull out method. I was pretty crampy and had sore breasts and symptoms starting about 5 days before my period was suppose to come. A little different for me but didnt think anything of it at first. I had what I thought was my period a couple days late but it was really strange for me. Usually my body goes back to normal but not this time after I get my period. About 3 to 4 weeks later and my breasts and nipples are still quite sore and heavy. With visible blue veins on chest leading to nipples now and think my ariolas are darker. I am exhausted, have diarrea, pretty nauseas, occasional headaches, frequent bathroom breaks, and just dont feel like myself. I did take a hpt and it came out negative recently. Am I going crazy or could I be pregnant or this this something else? HELP!!!
