Super frustrated

This past month, my infertility has been a cause of major frustration, because my doctor seems so lax about it. She brought me in for a blood test on my 3rd day last month, everything was normal. When I called for clarification (because her notes said nothing except "normal range. See you on your next visit." Which wasn't scheduled), she said, well we need blood tests on your 5th day. And it was my 5th day when I called, so I said, "Well, that's today. Squeeze me in!" To which she said they couldn't because they were short staffed and had to wait another month. Now I'm waiting until AF, who's supposed to be here in the next few days. If I start today or tomorrow, I'll be in the clear (but I'm guessing she's still going to be lax about the blood work and say need you day 7, wait a month to schedule). But if I start Wednesday, when the app is predicting, I'm SOL, because the lab will be closed for Sunday and the holiday. I'm on month 16 going on 17, and I'm so frustrated with everything. The doctor. The process. Everything.

My daughter is already almost 6 and we've been trying since she was 4 , because we didn't want too big of an age gap (we delayed a year because of COVID, and my husband losing his job in 2020). But at this rate I feel like it's not going to happen, and my doctor couldn't really care less.
