TTC after miscarriage

Kr

Alright guys, I had a positive pregnancy test on June 9th, I would have been about 4 weeks and the next day was bleeding, all bleeding was light and I never filled a pad once, I stopped bleeding 4 days. I started taking ovulation tests on June 21st, my <a href="https://play.google.com/store/apps/details?id=com.glow.android">Glow app</a> says I'm supposed to ovulate on Thursday but Ovia says Monday (Tomorrow) so I started taking the tests on the 21st. Here is the progress. Can I get any kind of input from the TTC/Glow community as to the LH Surge?? I'm thinking June 23rd. Just seems like it might be to early to ovulate sense my miscarriage. Thank you for any advice.
