Lots of questions- please help!

I found out Saturday that I am pregnant! My last period was on November 21st so this app says I'm six weeks pregnant, is that fully accurate?

Also, I'm cramping so much and so bloated. Bloated like I've never been before. The scale says I'm ten pounds heavier! Is this normal so early? Like I look like I already have a bump!

Also, is it too early to tell immediate family? New momma here and just have a lot of anxiety and questions!
