I've been on it for a week and a half. Today I decided to look into whether it could be the cause of my recent (and uncharacteristic) bitchiness and over-emotionalness. Sounds like it. I've also experienced some mild brown discharge.. I think it could be blood spotting, which I've read is common for someone new to birth control. So far, if this is what's making me impossible to be around, it's definitely not worth it. Back to condoms for me...
