Lower pain

Okay hi you guys, so I have a bit of a problem or I'm not really sure what's going on, but today I've felt a very very mild to sharp pain in my lower abdomen on my right side the pain comes and goes, might I add I finished my second round of clomid earlier this month on the 10th, so as of today it's my cd 19, and on Friday I go to do my 21 day proestronge test, which is my cd 21, does it mean right now I could be experiencing ovulation pains? At one point it hurt so bad to walk I could feel it...if anyone have any insite please feel free to answer, I repeat this is my second round of clomid and I took 100mg...
