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. He tested me and said "negative, but faint positive" and told me to keep testing. The dr also told me he thinks it's previous HCG. 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? I'm thinking it's residual tissue and that it could lead to an infection. I called my Dr but there are no appointments until next Friday. So I'm a bit stressed over this.
