Am i overthinking?!

Ashlee
So I am currently 5 weeks 3 days and am having some mild cramping that lasts an hour or so and it will go away. I also have crazy gas bubbles in my stomach and it keeps making noises! Are these signs normal? This is my first pregnancy and I want to make sure everything is going as it should! I think now that I have actually conceived and got that BFP I am more aware of tiny things happening in my body!
