hey, me and my boyfriend never use condoms but i recently got on birthcontrol. but as soon as i went on birthcontrol like 3 days of using it my boyfriend came in me, i was worried because also i was on antibiotics. but recently i was having cramps, bloating, fatigue, back pain, headaches,... was the birthcontrol working? im still waiting for my period to come. i was told birthcontrol dosnt start to work until 2 weeks of being on it. so that freaked me out even more. i just need answers, should i be worried?
