TTC after MC

Alisha • One son...2nd 🌈👶🏽 on the way and it’s a girl!!! 🎀
I know it hasn't been that long but I'm getting discouraged already. I had a MC late DEC and I've had 2 cycles since but I've been tracking my ovulation with opk but nothing!! 😔 why am I'm not getting positive tests!!??  I'm starting to think my body is just not ovulating yet but I've heard u are supposed to be really fertile after a MC....
