Tickle Feeling on side

Has anyone experienced a sort of tickle feeling on their sides before? I had this on going tickle/tingly feeling for a few days last week (about 8 days past ovulation). I've never experienced it before and it was specifically on my right side kind of at the level of my belly button. We're not currently TTC but we are not on BC and did have sex the first day of my fertile window. Just curious if anyone else had had this before or not/what it could be from?
