Weird Vagina Help

So I had my first 2.5 years ago. I’m currently 30 weeks pregnant with my second. I looked at my vagina once after birth and it was a huge mistake so I never looked again. Until today. I have a bit of a heavy feeling, but no pain or discomfort. I looked and it almost looks like there’s no actual vagina hole? It looks more like there’s a wall there instead? It’s weird. Obviously there’s a hole or I wouldn’t be able to have sex and I have sex around once a week and it doesn’t cause me pain. I have super bad insurance, so I can’t afford to go make an appointment with a doctor to look at it. And I do home births, so I’m thinking of just asking my midwife at my next appointment (3 weeks). Does anybody else’s vagina look like this? Is it normal? My only concern is if it would complicate the birth. I’m just wondering if anybody has had something like this?
