I’m concerned

So in one of my previous posts on a different group people told me there is no way I got pregnant from doing things with my bf (we didn’t have sex he just fingered me) and a lot of people were saying I should get on birth control. So I talked to my mom about it and said I wanted to get on it cause my period was too irregular (which is true). I’m on it now but I have been having weird symptoms. Like I am more sleepy and having cramps where my kidneys are. I am also more hungry. I was trying to look up what these could mean and the only result I got was that I could be pregnant. So now I’m super worried again. I have been takin birth control for almost 2 weeks now Are these normal symptoms from startin birth control or is it possible I’m already pregnant? I take my birth control everyday at exactly the same time 4:00pm. I have missed a day or anything. Please help ease my mind or just help me understand what’s going on.
