Pooting Vagina I guess?

Shani
Okay so, I've been cursed in my past with 4 miscarriages. I'm only 24, yes it sucks tottaly! 😢😢 I have a question has anyone ever had a pooting vagina then found out they were pregnant? I'm like it can't just be me can it? Like with 3 of my pregnancies either before I find out or about 2 weeks after finding out I was pregnant I experience a pooting cooch! Like wtf is that? I want to know. Please advise.  (Not pregnant now still TTC)
