Crotch pain at 34 weeks

I have this Achiness/soreness in the circled areas. It not in my vagina just on the outsides. I’ve never been able to find anything as to why. I was told it’s just from the weight of the baby.. it’s usually at night. It feels like I accidentally did the splits and pulled a vag muscle. Do others get this feeling?

I don’t think I’ve been able to explain it well to others I ask because it doesn’t seem to have a name.. so I used a pic this time to show where it’s coming from.
