Help!!!

I’d say a little more then a month ago I had lost my birth control missed 5 pills had a very short period got on stronger pills that I got from my sister and then and 2-3 weeks ago I started my regular smaller dose pills spotted once pink blood and now my boobs are killing me they feel swollen and I’m soo bloated and nauseous and I really badly want pickles yesterday I ate fruity pebbles with sour cream and onion chips I have no idea what I was thinking I can’t get a pregnancy test at the moment but I’m supposed to start my period in about 10 days I have had my period since the last period after I lost the pills do you guys think I might be pregnant
