Question, ladies.!

So, I want to know if you guys might think I'm pregnant. I know I see these posts all the time and I hoped I wouldn't be one of them, but here I am now.! So I'll start off with this, my period was supposed to be last Tuesday and it's been five days. I don't have any cramps what so ever and yes, I've been sexually active within the past couple of months. I have gained a whole lot of weight in the past week, don't know why.! I work out everyday and eat healthy.
