F, 32 years, married for 6 yrs, TTc since 3 years. Done Multiple IUIs all have failed. My hormonal tests, tubes , uterus all ok. He has sperm motility issues We seem to have conceived atleast 1-2 times in IUI but have had delayed periods. We did have progestrone supplement at that time on doctor s advise. We have now taken a break from all treatment and are concentrated on increasing frequency during ovulation time. My question is Is it ok to have Progesterone supplements on your own ? I track my ovulation by the appearance of my EWCM
