Here are the details. My gf and i have recently become sexually active. She started the pill mid cycle and we did not have sex til 3 weeks after(for many reasons). During the second week, she missed a day but started taking them the next day and we waited another 6 days. This is the only one she has missed. We had sex and used birth control, condoms, and I pull out before ejaculation. During one instance there was a light red fluid discharge. She is 4 days into plecebo week and has not gotten her period. Should i be worried?
