Should I get birth control to straighten out my Ph balance?
I wanna get itstraightend out because I'm starting a week earlier then I should and I don't like it one bit Bc I hate bein on my period and I'm starting way to soon but any ideas on what to do? Should I get birth control or is there anything else?
