19mm follicle

Beth

I took femara 5mg on days 4 to 8 and today is cycle day 18. I'm at the doctor now and I have one dominant follicle measuring around 19mm. I had a blaring postive opk test last night. We are going to probably trigger when I get called. Is this good? I feel like maybe I should have more follicles to have a better chance? Never triggered before
