Lh hormone fluctuating before ovulation surge

Nicola

Hi all

I just did my first round of Clomid 50mg and went to the doctor Wednesday for an ultrasound follicle check. I had 8 follicles and 2 that were or great size. My doctor told me to use my ovulation kit twice a day and have sex when I get a positive read. I’ve been testing since Wednesday and it’s fluctuating so I confused if I missed it or is this normal before a peak?
