Fifth Month TTC

Me and dh have been ttc for 5 months now. I've gone through removing polyps, increasing my iron levels and using preseed to reduce pH levels in uterus. This last period, I used preseed to help with keeping sperm viable during ovulation. (Although semen can live 5 days, if ewcm is not present the vaginal cavity will kill it in 30 min pH of uterus must be alkaline for sperm to survive long enough to enter uterus during ov.) With each ov I had ewcm 2dpo and 4dpo. This last attempt I didnt have any. Progesterone is released when fertilization occurs. Progesterone causes dryness. So I'm hoping in another few days I get my bfp

Curious if anyone had something similar prior to bfp.

I've read that there are no symptoms with fertlization until implantation but can't help thinking that I felt naseaous and cramping
