i've been taking birth control for about eight months now and I've never had a problem with sore boobs until my period was about to start but now I'm in the beginning of my ninth month and I'm starting my second week and my boobs have been sore . I take my pill every day at the same time which is 8:00 PM and I've only missed a pill once and that was when I first started . I do have sex without a condom but I make sure he never ejaculates inside me and he always pulls out and comes nowhere near my vagina . I'm concerned about my boobs being sore and I wanted to ask if I should be worried or not or maybe if it's just the hormones changing my body. Or maybe my boobs are growing I don't know .
