Okay I didn't have a period in April at all....so like last week I took two tests on different days and got negative on both. Yesterday after My fiancé and I had sex I had a little bit of really light red almost pink and there was hardly any of it when I wiped....so I thought I would start my period so I put in a tampon but a little while later when I went to the bathroom there was barely anything on there....just a little bit of light red and then it stopped after that. What's wrong with me?????
