After miscarriage...?

I had an incomplete miscarriage about 4 weeks ago (I didn't even know that I had been pregnant until my doctor did my routine pap and realized that my uterus was enlarged, at which point more testing revealed that the pregnancy had been spontaneously aborted at about 7 weeks). As I had no bleeding or ping of conception materials, I was instructed to have an MVA (same procedure as is used for theutic abortions) in order to make sure I didn't get an infection. I had the procedure on Friday, had some light bleeding over the weekend, and was feeling fine. Yesterday (Monday) I ped clots for several hours (none bigger than a quarter) and my bleeding was heavier than on the weekend. Today I'm also having slightly heavier bleeding, and I've had cramps for the past two days as well (although they're manageable - like period cramps). Is this pretty normal?
