Bulging labia around vagina ?

Maybe a little TMI but i was on the toilet for a solid 45 minutes due to constipation. 39 +4 here. I ended up feeling my actual labia with my hand after it feeling “off” when wiping and found that i was like bulged? As if i was literally pushing my child out right there. Now as I’m laying down it’s gone. Has anyone ever experienced this ?
