Larger Follicle Size (33mm) Still Ovulate??

Jacinda
I went in for my first ultrasound this clomid cycle, on cd 14, it showed 2 follicles that were around 13-14mm. Dr. Said not quite ready yet and to come back in 2 days later. So fast forward 2 more days and I was having a lot of pelvic pain and just a strange fullness feeling in my pelvic region. The ultrasound this time just showed one really large follicle at 33mm. My Dr. said that was great and he was happy with that so he gave me the trigger shot. Now it's been almost 3 days since the trigger shot and I still have that fullness feeling and I haven't really felt anything as far as ovulation pains go (which I normally do) my question is, has anyone else had larger follicles successfully release? Or was mine just too large and over mature to result in successful ovulation? Also, has anyone ovulated late from a trigger shot, if so how much later? Thanks!
