I’m a 36DD currently, not sure why my size matters in this situation, idk maybe it does *shrugs*

I got the Mirena(IUD) put in last spring and it has worked well so far. In so much, that I hardly even bleed anymore. All I get are the rest of the menstruation symptoms like cramps craving, sore boobs etc. My boobs feeling sore is usually one of the lesser symptoms I experience, as it only lasts a day or two and it’s not too bad at all. Since, I’ve had it put in, I did notice that my cycle has gone a bit awry, but it never seemed like something to worry about, as the doctor warned me that it would take a while for my body to get used to it. 

For over a week now, my boobs have been feeling ridiculously sensitive and irritable. They itch and become irritated even with my clothes. The slightest bit of weight on them hurts, and I can’t even give my husband a tight hug or let him touch them without feeling a good bit of pain. I don’t remember ever experiencing something like this before. 

I don’t know much about breast health, but I’m kinda freaking out. Are they growing again? Am I sick somehow? The only reason I know a woman’s breasts to growafter puberty is pregnancy, now I’m no expert, and I haven’t had any other pregnancy symptoms, but maybe I am? What else could this be?
