Clomid, progesterone pessaries & opks - help please

[2ndstreet]

Hello I was hoping someone might be able to give me some advice. I'm on my 2nd clomid cycle had 2 ovulation scans 1st confirmed 1 good follicle 2nd that I'd ovulated. D21 (on d17 as 6/7dpo) progesterone was 33 to further confirm ovulation, unfortunately started spotting that day & for next 7 until af. Fertility nurse has prescribed me progesterone pessaries to use from o to af to stop spotting. Last month had clear lh surge d10 this month now d12 and nothing. As its secondary infertility I have to pay £240/month for scans so as last month was ok hospital have left me to it. Not sure whether to keep testing and when to start progesterone and then whether to use as pessary or suppository- pack says either. Has anyone got any experience or advice?

Can't help on most of it, sorry OP, but strongly recommend using backdoor ie suppository. They absorb better (unless you poo it out, in which case I just used another), much less mess in your knickers, and won't (obviously) irritate your cervix which can be an issue if you use vaginally.

Would recommend scans if you can just because clomid (esp cumulative use) can thin the lining, so it can simultaneously 'work' (ie stimulate ovulation) and make it impossible to conceive if nothing is able to implant

Good luck x
