Seriously frustrated with cycles

Candi • Baby one born March 2016! Was TTC for 20 months. Baby 2 born 6/2019. TTC for 20 months. Now TTC baby #3. Scar on my tummy is from surgery I had as a baby.
Here's my cycles since we have been TTC. I was never over 34 days before BC and on it I was 28 days. It's really frustrating me that I'm this irregular now after stopping it and that we are wanting a baby. :( idk what to do. My dr (OB/GYN) won't do anything until we are TTC for a year. Our family physician checked my thyroid last month and it was normal. I don't want to wait a whole year. I know that selfish and petty.
