Ok so I had sex then 2 days later my period came on ... Everything was normal then my period came on for the next month normal ... But like 4 days after my period went off I would see faint pink blood as I wiped . The color got to the color red then like after 3 to 4 days it stopped . The 4th day I went to the dr and took a pee in the cup and he said that he didn't find anything and I could understand why simply bc I stopped bleeding at the dr office but he said he ran a pregnancy test as well and it came back negative but then called back like 8 days later saying that the test was positive ... What could this be ...??
