Round 3 100mg Clomid

Bridget • I`ve got faulty bits. Struggling to conceive. Hopefully we can get pregnant this year.
Okay, I have a question. Some background first, this is my third round of clomid but second month at 100mg. I ovulated last month at this dosage but I'm not having the same intense pressure this month like I had last month. My question is has anyone not ovulated after ovulating the month before at the same dosage? My cd 21 is on friday the 17th.
