Body is acting weird

So 4 days ago I went to the doctors found out I have a UTI & yeast infection , and a day later found out I have strep throat. I took the one antibiotic for the yeast infection and I’m still on my uti and strep antibiotic, seems like the yeast infection isn’t letting up, can a uti have the same symptoms as a yeast infection ? Also my period isn’t due for another 10 days and today out of no where I saw that I bled thru my underwear and pants... could that me a side affect from all the anti biotics? or maybe from the yeast or uti??? Or could my period just be coming early? Idk just so confused right now on what’s going on with my body!!
