My period came today, almost 6 weeks (41 days) after my D&C. If you considered the spell of severe cramping and bleeding that I experienced 5 days after the D&C as when my body finally figured out that I wasn't pregnant and started to "reset" itself, this cycle is only a couple of days longer than my non-medicated pre-pregnancy cycles. This seems to be a fairly typical flow for me, however, I did have some crampiness, backaches, and heavy spotting over the past few days. My skin was also quite inflamed, and has been for the past couple of weeks. I hope this will calm down soon.
I'm not sure whether it is just a coincidence that my period began to come on just after we found out the results of the karyotype on our baby--just after I found out that our baby was a little boy with trisomy 21. Perhaps it was just the way things worked out. Or maybe, after finding out more about our little one, my body was just finally ready to let go.
