TTC after Miscarriage

I've been browsing all the related posts on here for hours. I've googled it (not always that helpful). I've talked with Family. The only thing I haven't done is talk to a doctor (haven't been able to schedule me). My question is how can I use this app to correctly judge my ovulation after a miscarriage? I can't count my miscarriage as a period, right? It was my first pregnancy and first loss. I want to jump right back in to TTC. I've gone 25 consecutive days with no spotting or bleeding. I have no idea when to expect AF. Looking for any and all leads!
