Boobs getting bigger

So I got off the pill back in August. Lately my bras been feeling different and annoyed me more than usual. Went to buy a new bra today and it turned out that my boobs now's 2 cups bigger than when I was on the pill (no wonder that my bra was annoying me). I still weigh the same or less than before so that's not why. I think it's the hormones that turned to normal that did it.
