I’ve been having Braxton hicks contractions as well it started early with my first pregnancy as well as my current one. The pressure in your vagina area could be baby, mine is laying low and that’s all I feel and it makes me feel like I have to pee even when I don’t because of how much pressure he’s putting there.
Maybe do a UTI check just to be safe too
I'm pretty sure I've been feeling Braxton Hicks this week as well… Ive also been feeling an odd feeling down there, almost as if baby is trying to crawl out. 😆 I’m pretty sure she’s low and it’s from her moving about but have no idea. It’s sounding similar to you so hopefully it’s normal!
It might just be baby pushing against your bladder and that pressure is kind of radiating? I had a similar feeling last week (19w) and it went away, but def ask you doctor for peace of mind if it’s persistent.
