Jelly like discharge

So my last period started on March 2 and according to the app I ovulated last week. I just got off birth control last month after being on it for a year and today when I was about to get into the shower I noticed a pretty good size kind of jelly like ball that felt like mucous in a way ? I’m not sure what this is as I have never had it before even before I had gotten on birth control. Just wanted to see if anyone else had this before and know what it could be ?
