30F suffering from recurrent UTIs, going crazy

I’ve always been the type of person who has gotten UTIs, but when I was younger it was probably once a year. At 26yo I started dating my now husband and began getting recurrent UTIs pretty soon into us dating. They started out as once every 4ish months and later became monthly. I was put on Hiprex for about a year which actually did greatly decrease the amount I got (I got maybe one on this medication). In July I had my IUD removed because it was malpositioned. My husband and I aren’t TTC but plan to soon so I didnt have a new one placed. My GYN urged me to stop Hiprex since there isn’t data on how it could affect fetal development. So I did, and i honestly Thought I was out of the woods and could stop the medication as I’d stopped having them. Lo and behold, I’ve had one a month since stopping Hiprex.

My husband and I have both been tested for STDs, all negative. We had an extremely active sex life when we first began dating and I attribute that to the increase in frequency of the UTIs. However, I truly don’t feel like I can go on like this. I am a nurse who works 12h shifts. I have several weddings of friends coming up. I am now allergic to penicillin, Macrobid, Bactrim, and resistant to cipro. I feel like I’m going insane and will never be able to live a normal life. I take probiotics, cranberry pills, pee after sex, use d mannose, drink probably 3L of water a day, am extremely hygienic… I don’t know what else to do. I’m at my wits end. I don’t even think my UTIs are related to sex anymore as they seem to just appear two-three weeks after I’ve finished a course of antibiotics and are unrelated to the timing of intercourse.

No one will take me seriously and I can’t get in to see a urologist until February. My gyn and PCP just keep testing my urine and sending me abx. I am starting to wonder if I have an anatomic abnormality…

Can anyone relate to this?? Does anyone have any advice of something I could try other than everything google and the typical doctor suggests?
