I have had two m/c. The first, I bled about 2 weeks, with full-on cramping and heavy bleeding with clots and "pieces" (sorry for the TMI). The second was really strange, it was lighter than a regular AF...and I even convinced myself that I must be still PG, and started buying PG tests. But, no...I don't know what was up, but my next AF was alot heavier...and it was clear that it was all over. I guess it just varies. I heard it isn't uncommon to come and go for a bit...but, if you start having pains...see your DR ASAP. (hugs)
