Please help !!!!

Sierra • 21😊, had my rainbow baby (omphalocele warrior 👼🏼💙,early misscarriage on May 28th , 2020 🥺

Can one of you ladies help me ! So I had a baby back in December after 4 rounds of letrazole and provera ! Sadly my sweet boy passed at 8 months and we are trying again !! I started my provera and I had a positive ovulation ? Anyone know why ? My other question is I ovulated my first round but wasn’t actively trying till about the 3rd month which by then my progesterone at cd 21 was 4.20 my dr said was normal for me ! My main issue is immature follicles and crazy out of wack periods ! Do u think this go round may happen faster ? Since I’ve already had a baby , my regimen was take provera cd 35 if no period then take that for 7 days ! Once I start my cycle start letrozole on cd 3 ! For 7 days ! This time I took it on cd 38 woukd that even make a difference ?
