Pregnant or not

My mom told me that I'm starting to eat alot & gained weight , i have no symptoms of pregnancy like morning sickness or etc BUT my boobs is sore & when i press my boobs there's like a milk and i did my pregnancy test all came out negative and it's been a month & yes gained weight and my tummy ISTG looks like I'm preggy lol ... Should i consult a doctor ? P.s my period hasn't come since last month ..
