Hi all, I had a MC 6 weeks ago at 7 weeks. Over the past the last week, I've been having on/off cramping, bleeding (not enough to fill a pad), hot flashes and for the last two days feeling dizzy/fatigue. I did a pregnancy test on the 4th which was faint positive, but while at the drs on the 6th I mentioned the positive test. I tested after a few days and the lines have become darker. I did a did two clear blue digitals 7 days apart. One said pregnant 2-3 and then the other pregnant 3+. Since then the pink dye test have become darker instantly after doing them. I did a clear blue blue test today and it was way darker than on the 4th. Could this be HCG lingering?
