Swollen Vagina

Hey mommas, so I am currently 26 weeks and 2 days, and have been experiencing so much discharge a day that I have to change my undies every 12-14 hours.. it’s 2-3 times the regular amount I had before getting pregnant. Not only that, my vaginal lips have become swollen.. it’s not painful or anything, but it is something I just realized. It’s the outer lips and the skin above the clit. I don’t know if this is something that’s normal, or not. I haven’t had sex in nearly a month, so it wouldn’t be from that. If anyone has any advice or has experienced this or something like it, please help!
