Tori

So I felt something was off a tested and seriously got a positive before the test even finished. I was so in shock that I took another one and same thing. I have no symptoms besides cramping and slight nausea I never know really when I'm supposed to get my period but glow said in two days. Is this normal my last period was Dec. 6 this is nothing like my first pregnancy I also have been taking biotin for a week if that matters thanks so much I obviously can't go to my doc til Monday
