D&C 12 days ago

Ronna • SAHM to my amazing 3 year old Princess. Baby Borja #2 on the way. Due 12-31-17
I posted this on the loss section but only got a few responses, maybe you guys can shade some light!
For some strange reason I took a CBE and got a super solid face on an OPK like high peak smile! 
Does that mean I'm ovulating already or is because of the HCG hormone, I was like 8 weeks by my LMP but 6 at D and C, I guess I could get a dollar store test to see if it's out of my system, anyone have any advice can I really be ovulating 12 days after???
