Swollen down there 🙈🥺

Hi everyone, a little TMI. 🥺

So..... I just came off my period and it was the worst period I’ve experienced. It was a shorter period and more intense. 2 days after my period finished my BBT spiked very low to a 97.20. I’ve never had such a low bbt. I then began experiencing pain on my vagina when I walk or sometimes if I sit too long. I realized my right labia (the inner and outer folds of the vulva, at either side of the vagina) is swollen. When I touch it, it hurts. It looks like a swollen vain. It’s almost like a bump but not really. Hard to explain. Comparing it to the other side, it’s very swollen. My lower back is also hurting. And I have weird feelings in my lower stomach. This has got me worried. I don’t have any symptoms of a yeast infection or anything. Should I go see a doctor or just wait it out?
