Follicle Growth

Lisa

Clomid 50mg day 3-7. I went in on Tuesday for my Cycle Day 9 US & BW and I had a 13.7 follicle in my left ovary. Nurse said my BW showed I was ovulating on my own so to BD that night and come back the next day. Yesterday it grew to 15mm and I will BD tonight and go back tomorrow. Will I still needy trigger shot if I ovulated on my own???
