So my husband and I had unprotected sex about 31 days ago. I took the morning after pill 2 days later. about four days later i had a period... It was pretty normal compared to my regular periods. about a week later i started having pregnancy symptoms...tender breast, tired, alot of headaches. Then i started pooping 2 or 3 times a day...more soft than usual. I started spotting three days ago.. Its a dark brown color and 2 0r 3 drops a day. I have taken 5 pregnancy test and all negative! Something is different with my body..could i be pregnant?? or is something else going on?
