Swollen labia majora ☹ A bit tmi..

DM
So as the title says.. I'm 28weeks +6 today and last night I couldn't sleep so I did a little exercise. idk if that has anything to do with it but the left side of my labia majora is swollen..i didn't realize til this morning because I felt a bit uncomfortable, it doesn't really hurt though,it doesn't look like a lump or cyst. I don't know whats wrong 😓 is that even a pregnancy thing?? Anyone else?? Sorry ik the topic is weird 😅
