Hi chat
I've heard of the post coital but not tried it. I figured if cm is the issue then the solution is iui and I'd rather put the money towards that instead. For some reason uk clinics don't do it really and I'm unsure why.
Tests I've done on Nhs and privately:
Transvaginal ultrasound to check uterus and ovaries
Hsg to check tubes
Blood tests for prigesterone, fsh, lh, thyroid, prolactin, std screening
Saline ultrasound- like transvaginal one except they put saline in your uterus so it gives a better picture for checking fibroids and polyps
Amh blood test to check reserve
I'm unexplained too. Though Amh was low for my age. Good luck hun.
