Does this sound normal? (clomid related)?

I had my period on January 18th - 24th. I took clomid on days 3-7 (jan 20-24) then from CD10 on, I have been taking OPK's daily around 2pm. They have ALL said negative except for the very first one I took ( But i think it was a false positive) Now, today, on CD18 My right ovary feels like someone is trying to rip it out of my side. It is fairly painful, and constant. Last night (sorry TMI) my boyfriend & I BD'd and it was so painful during that we had to change positions multiple times in order for him to "finish" I am thinking I am ovulating, and HOPING it isn't a cyst. I was put on clomid to get a better quality egg, not because I didn't ovulate on my own. Could these pains be ovulation? I got a negative on an OPK again today... but it feels similar to ovulation. It hurts to even touch my lower abdomin. Any Advice? or experiences? did you have such pain then find out you got pregnant that month?
