Ovulating after day 23

So I have been trying to conceive about a year now. I use clear blue to track ovulation. They don’t pick up a peak until after day 23 every month... my high days start at about day 10. So I go through ovulation test like crazy since I don’t peak until real late! I haven’t conceived even when I find my peak so late and (bd). I went to my doctor and she did blood test which I called to get and the front desk just gave them to me and blew me off... my option given to me was to get a day surgery to check for endometriosis... which is going to cost $4,000 with my insurance... does anyone know a reason for such late ovulation and if that’s causing me to not conceive? I’m including my blood test just in case someone has experienced this and sees any red flags that could help! I just don’t know if I should see another doctor or if I really need the surgery! Thanks in advance!
