I'm 29 weeks and I just noticed today. I think it's normal for pregnancy
I had this issue and I talked to my doctor about it. She told me it is yet another symptom of pregnancy. Where some women get it worse than others. I had that and it sucked. It goes away though, don't worry. Just continue to drink plenty of water. And you can use cold packs if you feel really uncomfortable. No ice or frozen though, they can cause more harm than good. And I like to take hot baths twice a week so I'm not sure if that may help you out to stay relaxed.
If its only on one side of your vajayjay it could be a swollen duct which is called a bartholins cyst. Which happens usually from a build up of fluid down there.
One side of me was swollen , I thought I cut myself shaving (since I can't see my VaJJ any longer) or had an ingrown hair, i had my husband check it out and he said nothings there. Im only 29 weeks. From my research it could be a lot of things including a bulging blood vessel, swelling inner and latter labia is common and most of the time nothing to be concerned about. Maybe try a warm bath? That helped me!
Its normal, I was swollen for a bit down there too. Dr said it could be many things so don't worry so much. What I did to help with the swelling and might sound crazy is put an ice pack on it .
It's probably almost time to deliver. I know it's earlier than you are expecting, but I was swollen there for about 3-4 weeks, and I delivered at 37 weeks. I think it sounds normal, and I'd do "other things" with ur BF to hold him over... lol hope it helps
