Missed Miscarriage & TTC - questions & advice needed

Sam
Hello all, 
I had a missed misscarriage at the end of February. Took forever to recover from surgery and this is our first month of TTC! However, I have been obsessed with tracking and OPK and have not once this month gotten a positive and it's stressing me out a bit. I'm worried that I did not ovulate or won't and I only have about 10 until UF. Anyone in the same boat? Or did everyone ovulate right away! I'm just not sure what to think. 
Any positive thoughts and or experiences would be appreciated. Just don't have anyone to talk to scout this. 😩
