7 weeks

Kristen 💕⚡️
I'm 7 weeks pregnant and this is my first (what seems to be) successful pregnancy, my last 2 I miscarried before this point, so I've never experienced the side effects. 
Is it normal to bleed on and off every few days? I also cramp from time to time. But the cramps and bleeding aren't at the same time. 
I was just hoping someone could give me some insight as to what's normal and what's not, I'm trying not to google because I know there will be something that will scare me.
