Clomid ovulation

I finished my first round of Clomid after trying to convince for 10mos and being diagnosed with PCOS. I use Clearblue Digiatal ovulation test. Sunday cd13 was low fertility, cd 14 went to peak, and Tuesday cd 15 went to high(used a different kit bc I thought it was faulty). Does Clomid make you ovulate sooner? And should I keep tracking through the week in case it was a faulty test? I feel like this has consumed my life, I can feel for the couples who try for years....
