Pregnant?

Today and yesterday I've been having this raw feeling on my right boob when I'm wearing clothing my areola isn't darker and no other changes in my boobs. And I've thrown up a couple times and have been having frequent headaches. And recently, for a couple days now I've been having a fluttery feeling on the left side of my stomach. I haven't had my period in months, not unusual for me because I do have irregular periods. I thought I was starting my period a couple months ago but it was red color blood when I wiped not brownish or anything. That only happened once. I may be overthinking it but wanted opinions. Does it sound like I'm pregnant or am I just paranoid?
