weird cramps / sensation ??

As of right now I'm about 4dpo. I had protected (condom) sex on my ovulation date , a couple hours later we had sex again , this time he started without a condom and put one on and ejaculated into that. I understand that there could have been left over sperm from the first sex session in his precum, I was also on a vaginal ovule for yeast infection and had taken the last dose the night before, there was still some of the medication left inside of me when we had sex, the doctor did say that it could effect the reliability of a condom due to the oily consistency, as it could potentially break down the condom, but the condom did not break  .. we are not TTC but we also are not , not trying . I'm not on any form of birth control. Because I'm only 4dpo I really doubt this has anything to do with possible pregnancy as it's far to early to have any signs as I would not even have implanted yet . We hadn't had sex in about 3.5 weeks before that point due to a yeast infection so there is no way I could have gotten pregnant earlier on. Last night , which was about 3dpo possibly beginning of 4dpo I started getting this twinge feeling , almost like a mild pinprick sensation in my lower right abdomen ... definitely in my uterus, tubes or ovaries . Is there any way I am experiencing ovulation cramps at 4dpo ? I know I forsure ovulated 4 days ago due to the consistency of my CM . 1 day out of the month I get snot like discharge that comes out in a clump and that corresponds with my ovulation day. Is it possible to get cramping at 4dpo if I was to conceive? I'm confused as to what this cramping is , it doesn't really feel like period cramps at all so it isn't early pms. 
Update: my last period started on January 4th and was a normal period.  the last time I had sex before this most recent time was January 1st
