Fourth cycle of Clomid

Megan

I have two questions, but first the back story. I am on my fourth cycle of Clomid. I did one cycle of 50mg (didn’t ovulate) and then two cycles of 100mg (didn’t ovulate the first one, but did the second one). This time, my doctor put me on 150 mg.

Question #1: Is it normal to have blank ovulation tests up until ovulation? I took Clomid days 5-9 and today is CD 17. So I’d assume I’ll ovulate soon, but all three tests I took today were negative. The test line didn’t really even show up. This leads me to my second question.

Question #2: I tried to Google this, but it proved to be too difficult. If I ovulated on 100mg last time, that means I will ovulate at 150 mg, right? Or is there a chance that I could not ovulate at 150mg?

I’m feeling very frustrated!
