Yesterday morning I tested positive with a rapid test. It was very faint, but it was there. My morning digital test said negative. I tested again at night with a digital and it said pregnant. I have been having bad back cramps, which I get when I am getting my period. My test lines are still very faint. This morning I had some reddish/brown discharge in my undies and when I wiped. Then it completely stopped. Fast forward about 7 hours and same thing when I wiped, but not in my underwear. AF is due Thursday, and I’m starting get worried. Any advice?
