Help!!!!!

Hey ladies, so i have a question I’ve been on Lo Loestrin Fe for about 6 months now. Everything has been going ok but I do have a few problems with this BC. I have pregnancy symptoms from time to time (which i am not pregnant) my breast randomly get sore and hurt also my nipples close to my period. I have 2 more weeks before my period but I feel like shit. My breast hurt a little, I’m tired, irritated and not really eating. I also notice today walking by the mirror that I am getting fat. Is this normal? Should i take pregnancy test?
