27f vaginal atrophy due to excessive antibiotic use

Hello, I finished my ureaplasma treatment (a month and a half worth of abx). Antibiotics wrecked my flora and I got Ovestin prescribed by my gyno because nothing else worked. Experiencing vaginal burning and UTI like symptoms (clear urine culture, no bv and yeast). Used Ovestin for 7 days but my period started and symptoms came back day later. Asked my gyno if I should use it for another 7 days after my period but she said only twice a week. My symptoms are severe can I use ovestin as I need it everyday because I'm in my twenties or is it dangerous? Thank you for your answers

hello, what symptoms do you have?
