It could be from the yeast infection so you should contact your dr and get some medications. Also vaginal swelling and pain is normal in the 3rd trimester so it could just be normal hormones causing it and the yeast infection making it a little worse.
I think it could be, but I'd ask the doc
Hip and vagina pain is normal at your stage of pregnancy- yeast infection or not.
Yes this can be a yeast infection and I had something similar in my first pregnancy. My dr recommended thrush treatment and hydrazol cream and that helped. Ask your dr what they think. It can be quite painful so hope you can clear it up soon. Good luck
