One quick question

Justine

Hi ladies. So I do not have a regular cycle. Today is cd18 and I really don't think I have ovulated as I use clearblue digital ovulation tests and never got a smiley face yet. My bbt is all over the place it goes up and comes down. Oh this is also my second month of taking fertimod. What is the latest cd you can ovulate. Would really appreciate some advise.
