Worried about the feeling in my lower abdomen...

I've been feeling pressure in my lower left abdomen, right above my hip for a week and a half now. At first I chalked it up as ovulation pains (ovulation was confirmed through bloodwork), but it hasn't gone away.. it sometimes feels like a little balloon is there when I breathe, and I occasionally feel tickles there. Just worried what it might be because it can't be related to ovulation still, right? :( this was my first round of clomid, too. Did anyone have this happen to them while on clomid?
