Does anyone know what’s going on?

Lately my boobs seem fuller and heavier. My periods apparently in a little less than 2 weeks, yes I do track it. I’m sexually active but we use condoms and are very careful. I took plan B around easter. I don’t think I should be pregnant but is that a possibility? I’ve also been a little moody and more tired lately. My doctor can’t get me in for another 3 1/2 weeks. Thank you
