Am I pregnant or is it birth control?

Hello! So I started birth control for the first time in August (I’m on my third pack). My boobs have doubled in size and they have been sore to touch everyday since I started bc and they keep growing. For example, I was a 32B before bc and I wanna say i could maybe be a 32D now. Yesterday I woke up with a yeast infection, which I tend to get yeast infections because of the antibiotic i take everyday but I haven’t gotten one in months. This yeast infection is the worst one i’ve ever gotten, (TMI) i can barely even wipe. I took a 1 day treatment of monistat last night and when I woke up this morning and it was even worse so I bought a 3 day treatment and anti itch vagina cream. However, my bf and I of two years just started having raw sex(he pulls out). Is this all just symptoms of birth control and my antibiotic or should I be worried?
