I recently started a new birth control called loloestrin last month, and I took it every day, but not at the exact same time. I am sexually active and do not use condoms, but my boyfriend has never came inside me (but I know there’s still a very slight chance of pregnancy from precum). I didn’t get my period last month, which I thought was normal. I wasn’t worried until my breasts started feeling very tender and swollen, and I started wondering. Could I be pregnant?? What are my chances??
