Should I be worried??

I’m 31w5d & last night I lost part of my mucus plug. I was told it was normal & that it regenerates. But when I just went to the bathroom I noticed that my labia majora (the outer lips of the vagina) & labia minora (the inner lips of the vagina) are swollen & there’s a lot of pressure down there. It doesn’t hurt unless I push on the area that’s swollen. I don’t have any weird discharge (other than the mucus plug last night), it doesn’t itch, it doesn’t burn & there’s no funky smell... just kinda worried. Is this normal??
