Ovulation after MC

I had a complete MC at 10 weeks on September 14th. I bled until the 19th-20th. I had HCG test done on the 28th and it was at 11 (almost negative). I started tracking my ovulation by curiosity with the ClearBlue Advanced digital and got the static smiley face this morning. Could it really be my peak?

And for all of you who conceived right fter MC, did it stick? I’ve been getting divergent opinions...we’ve BD all week, because I was feeling sooooooo horny (lol) and I didn’t know I was about to ovulate. I don’t want to get pregnant and lose it again because we were too early after my MC😔
