Ovulating while on clomid

Are the lines getting darker? Im on cycle day 8 according to my doctor i should ovulate between cycle day 12-15. Im on round 2 of clomid (100mg). I have an ultrasound on monday wish me luck and give me all the baby dust possible. Can anyone share their story of getting pregnant while on clomid?? Oh yeah forgot to say i have PCOS and should be taking Metformin but i stopped like a month ago.
