Bulging/pressure down there

My vagina area seems to be bulging. Tmi but reminds me of the feeling after having sex and sitting on the toilet while relaxing those muscles. I can basically cup the area with my hand. My baby wasn’t that low at my last appt and doesn’t feel like he’s dropped any, but this is a new symptom today at 37 weeks. Anyone else? Didn’t experience this with my first pregnancy
