hello, i used to take a birth control pill called mycrogynon 30 but i changed it to one with a lowers dosage of hormones because i was sure it was causing mood swings. My doctors changed it to mercilon, however about a month after i started taking it i started noticing that i am suffering from extreme vaginal dryness. could you please tell me how i can sort this out or make it go back to normal again without having to use lubricant from the shops?
