A few months ago I had a d&c, and now I've been having a lot of tightness in my lower belly on and off, I'm bleeding bright red blood, and a few days ago I passed a thick tan ish object... no blood on it or in it. It felt rubbery... I inspected it... I really just want to know what going on with my body

These are good questions, and ones that you need to ask the doctor who did the D/C, when is your next appointment ?

I'm having an ultrasound on the 10th

What could is possibly be? Its freaking me out.
