I had a fair wait for mine and that was before covid really hit. I feel for you hun I really do. Chemicals are so heartbreaking when they keep happening over and over and also so frustrating, as like you said, you can obviously fall pregnant but they just don’t stick. My first chemical I ovulated on cd52, so to be fair I wasn’t surprised it didn’t work out, but then I didn’t ovulate for the next 3 months and the 4th I had on/off bleeding. I think it worked out over the year because of the anovulatory months I actually got 6 tries at it. 4 were chemicals, one I just didn’t fall at all and the 6th was my son. With dd3 I didn’t ovulate at all for 18 months. So I’m assuming there’s something else not right to be honest but I didn’t go for help with her. I tried Angus castus and it worked for me, I ovulated within the first month of taking it and it resulted with her. I was very lucky.
Sorry for the ramble but I just hope I can give you some hope that I'm sure it will happen for you and hopefully before you’ll need that appointment like it did for me. As hard as I know it is when you’ve been trying so long already. Im rooting for you so much
