Someone please help me 😡😞

So I had a miscarriage on October 10. I had a d&c; on October 12, and October 17 due to them leaving half of the fetus in me and it was necrotic and I wAs getting sick from it. My first period came the beginning of December and the only reason it came was because my doctor put me on provera to start it up. I was suppose to start on december 28.. well it hasn't showed. I took a pregnancy test on the 27 and it was negative. Took another on January 2nd and it was negative too. I've had cramps the past three weeks and my boobs are sore. Can anyone relate to this? Am I pregnant or is my body just screwed up?
