Could I be pregnant??

So I haven't had any of my normal symptoms I usually get when it's time for my period, no soar breast or cramps and my period is supposed to be in 4days.. I always get my symptoms before I come on that has been a norm for me.. And on top of that I weighed myself two weeks ago and I weighed 130 I've gained 15 pounds since then, I don't wanna get to excited but I'm kinda confused.. All I can do Is wait cause I don't wanna tell my husband until I get a positive positive
