Scared of Miscarriage- help

Hi ladies. I’m a plus size woman (247 lbs) and just found out that I am pregnant.. I’ll be 5 weeks tomorrow. This pregnancy was not planned. Im 27 and 5’7. I’ve been doing a lot of research and googling naturally and I keep coming across sooooo many women who have went through MC. I understand it’s common but it’s getting me rather down and pessimistic about my own pregnancy . I mean I have no real reason to assume I’ll miscarry but I undersrand being overweight doesn’t help. Any positive words or statistics are welcomed :)
