Post D&C ovulation


I had a D&C on December 29th after a failed pregnancy. My OB said my period should start again in about 2 months and that it was unlikely that I would be able to conceive before then, however I decided to take an ovulation test just out of curiosity today and it ended up being positive. Like super positive. Could I actually be ovulating again already or is there some other reason I could have an LH surge right now?
