URO probiotics?

I’ve been ttc for years. I got diagnosed with pcos in 2020 after having a miscarriage after ttc since 2014. Haven’t got pregnant since. But in the last 5-6 months I’ve been bleeding between my periods. My period has started lasting about 7-8 days then I won’t bleed for like 4 days and have light light bleeding for 3-4 days skip a day and 3-4 more days on and on until my period starts again. I started taking URO vaginal probiotics about 2 weeks ago but it’s for ph balance. My period was supposed to start January 2nd and I haven’t had any symptoms at all, but I started bleeding thinking it was my period about 2 days ago but I really think it’s just the “bleeding I have throughout the month” because I haven’t had any cramps or any symptoms that I usually get before my period. Could this be from the URO probiotics? Has anyone taken these and that happen to them?
