Not gonna lie but I'm sexually active at the age of fifteen, turning sixteen in two weeks. I have only been using condoms for the two times that I have had sex with the same guy. Today I just got the pill (for acne reasons AND to prevent pregnancy). I was wondering when exactly I should start taking them. The instructions are very confusing. My last period was December 3rd-7th. Today is December 20th. So when exactly do I start taking the pills? Do I wait for my next period or do I take them today/tonight?
