Late Ovulation With Clomid ?

Alivia

I’m on CD 17 after taking 5 50 mg clomid pills days 3-7 . This is my first round but my clear blue digital advanced test is still reading low, has anyone experienced late ovulation on clomid? and if so on which CD did you ovulate ?

Since last night i have been experiencing slight back pain , and a little breast tenderness, and i had a dime sized amount of CM come out last night , so i’m wondering why i wouldn’t at least be testing high?
