New issues at 30? Is this normal? Help

Hi all! Let me preface this by saying I’ve been to various doctors with no real success on getting advice or finding solutions to these new issues I’ve been dealing with since I’ve turned 30 last June. I’m desperate, so any and all advice is welcome.

I feel like EVERYTHING about my vagina suddenly changed last year when I hit my thirties and I’m struggling and so uncomfortable.

First, I’ve been dealing with recurring yeast infections, dryness and itchiness, sooooo much discharge but still feeling dry, painful sex, vaginal swelling after sex(my vagina literally looks like a balloon after sex, it gets so swollen)

The problem is, I thought all of those symptoms were because of the yeast infections but I just went in AGAIN to get treated, but all my tests came back negative for yeast and she did a full comprehensive panel to see what specific type of yeast if could be, so I feel like it was an accurate test. I waited a month after my last treatment was done to go back in just to make sure and wait and see. But it just is so weird that it came back negative cause I feel like I have all the same symptoms that I’ve been struggling with for months and the other times, I did have a yeast infection

I just don’t know what to do. We did a full bloodwork panel to see if anything was causing the yeast infections, thyroid checked, I’ve had every STD/STI test done, but everything came back normal or negative.

She put me on a low dose estrogen/progesterone birth control to see if that helps because I could potentially be low on estrogen which is causing the dryness but I’m not sure if it’s working/helping. I still have crazy amounts of discharge and discomfort/dryness. But supposedly no yeast. Im too afraid to have sex to right now because of how painful it’s been since this all started. I would love to have my sex life back again, but I haven’t been able to have sex with my partner for basically 8 months because of this.

I take probiotics, I only wear cotton underwear, I don’t use scented soaps, and I don’t use soap inside of my vagina, I know how to wipe, I feel like I’m doing everything right but we just can’t figure out what’s wrong and it’s driving me crazy.

Has anyone else struggled with something similar? What helped you?
