I saw my gynecologist yesterday about irregular periods and bleeding. Last month I only had brown spotting for 4-5 days, this month stopped my period and 3 days later, started right back up. I'll work out, and bleed after, have sex, bleed after. I finally had enough. I call my OB and discuss the issue, he says my birth control pills have been ineffective for me AGAIN - we switched pills about 5-6 months ago as well because they were ineffective for my body - and he's trying a new pill.
