After Miscarriage INFO

Sydney
For those of you who don't know: 
10/18 found out I was pregnant (4 wks)
11/08 1st ultrasound/great heartrate (6 wks) 
12/05 2nd ultrasound/ (10 wks) found out the baby's heart had stopped the week prior. 
12/07 D&C (bleeding lasted about 2 wks)
1/05 period started NOTE: my levels did NOT reach zero by this point. Period was normal. 
01/17 spotting began 
01/19 levels were 35
01/22 levels were 13 
I ovulated around the 17th and implanted after the 22nd. 
01/26 levels were 39
02/02 levels were 47. It was at this point that I was told this was a chemical pregnancy. 
02/08 levels were 34
02/15 levels were 33
02/16 spotting from 01/17 stopped
I will be getting levels done tomorrow (02/22) to see how my levels have fallen. 
So to be clear. You can absolutely ovulate with your levels not returned to below 5. 
Right now I'm being monitored for ectopic pregnancy, retained tissue and choriocarcinoma. I will keep everyone updated.
