No second period after miscarriage

Alison, 🌈 👶🏻 born 7/26/19

Can anyone tell me if they got there first period back normally after miscarriage but then second one didn’t come?? We had a miscarriage in April and I had a D&C; April 18. I got my first cycle back on may 13 but it was heavier than normal and wasn’t like my previous cycle before the miscarriage... well today is day 30 and it still hasn’t come!!! We had another miscarriage in December and everything returned normally then which allowed me to get pregnant again so quickly in February. Really worried this second miscarriage screwed up my cycle. I was always so regular and here I am day 30 and nothing. I also am 39 (today is my birthday) and made an appt with an RE after the second miscarriage and I needed to wait til the second cycle to start testing .... fact it hasn’t come back means I can’t start testing and we can’t start ttc again. Has this happened to anyone else? My re said if I don’t get it by day 35 they will prescribe meds to induce it. Any insight is much appreciated!!! I don’t wish this process on anyone.
