Cycle Buddies Anyone?

Hello All! 🤗 My name is KC. I am a software engineer in MD. I'm TTC #3. Found out I was pregnant on 7/21 (was 5 wks at the time) however on 8/6 I miscarried. Have been trying since the bleeding stopped on 8/9. On average my cycle is 28 days. According to 3 of the 6 period tracking apps I currently use AF is predicted to visit on 9/3. My doctor said to use the miscarriage as my period being that it lasted the length of my usual period it was just a week late. So I'm just looking for someone that could give encouraging words and help me through this process a bit. Thx You In Advance!!! ☺☺☺
