It sounds like it might be your period or breakthrough bleeding. I've heard that Depo can sometimes cause heavy periods. If you think you're having a miscarriage, take a pregnancy test. It will be positive if you were pregnant and are now losing the baby.

As far as your question, yes it's possible to have a miscarriage, but it wouldn't be because you had an abortion. Every woman is at risk for miscarriage no matter their medical history.

well what about my discharge.. it actully loooks like breast milk.

does that mean i am preg.?

There's no way for me to know. You need to take a pregnancy test.
