Hey guys. 9 days until my period.

My boobs have started to change colour and become enlarged however they often do before my period so idk? Today I've had pain and discomfort in my abdomen like sharp pains and then they fade, it's around my uterus area. My nipples usually stay level to the rest of my skin unless turned on or cold. HAHA but they're super sensitive and poking out a lot. Was just wondering if any of this stuff is valid or if it's too soon and to stop worrying? I'm young (17 almost 18) and he's came in me in the early stages of my fertile period. My family had high fertility though and so does his. Just wondering really. Period? AF? Or could it actually be something?
