Had unprotected sex on the 2nd, missed a pill the day before and the day of the sex. Af was due the 17th and didn't show, many pregnancy symptoms that even my peers became suspicious. Took a test and it came out faintly positive. On the 22nd I bled dark brown for a couple hours. And since then I haven't bled at all, not even a drop. Does anybody have any idea on what could be going on or know what I should do? I'm going to the doctors in a few days
