Possible pregnancy or something else?

Ive been on the pill for a year now but lately i havent remembered to take it at the same time everyday. Now im not sure yet if I am pregnant but I am feeling very sick mainly afternoon and night time as well as being very gassy and having that constant hunger feeling even when I feel full. I've been irritable lately about the dumbest stuff and I have sore breasts and nipples. I'm also getting these pains on the right and sometimes left side if my abdomen and an increase in watery discharge. I also find myself urinating frequently and having a heightened sense of smell. Smelling things I normally wouldnt find stinky. Does it sound like I could be pregnant? If I am I would be around 7 weeks
