Down Increase In Breast Size And Delay In Periods Mean I'm Pregnant?

Hello, i think i may be pregnant. bloated tummy, you see it pretty good with tight clothes, my boobs have grown really big in just a few days plus really sensitive, i have some areolas on the lower part of my nipple, so i didnt notice this until yesteday, ive gotten a few legcramps, i have morning sicknes coming and going all day, i have mood swings, my sleeping habit is a bit weird, i dont like the food i used to as much anymore.

I had my last period 6-7 weeks ago. I am on the pill, but i havent had any menstruation. by the way, i started taking the pills again around 4-7 days later than i should of have, also i can be pretty sloppy. im 16.
