Hi, I’m 10dpo and testing negative.

I’m on second cycle of clomid. Ovulation has been confirmed through scan/progesterone test. Eating so well, lots of fruit & veg, had 1 drink in 2months. Progesterone very high. We have sex every day in the week I’m due to ovulated but still not successful. I’m now 36 so feeling the pressure of my age. My partner had his sperm tested years ago which was fine. Anyone else been through this or know what could be preventing pregnancy? I did have a late miscarriage in 2021, not sure if that could have caused an issue.
