I Had A Miscarriage 8 Weeks Ago, I Took A

I had a miscarriage 8 weeks ago, I took a prescription to induce the miscarriage and bled for two week, although I cobtinued to have bloody discharge I had a ultrasound that showed a tiny piece remaining and a very small fibros, the Dr said he wasn't cincerbed about either and thought the tiny piece would flush out when I got my period. So i had my period around its scheduled time but when it finished I still had pink discharge. I called the Dr and he said it's just my body getting back to normal hormonal levels, but today I feel very bloated and slightly cramps!? What is going on with me?
