First time mum to be and only 4 weeks. Please tell me what to expect?

Al

Been trying for 2 years with a chemical 12 months ago and have just found out I’m 4 weeks and living in complete fear. Every niggle, pain, cramp makes me freak out. I can’t help but fear and assume the worst and right now I can’t seem to rationalise my thoughts.

I was hoping people with real experiences could tell me what sort of weird and maybe scary things they experienced but went on to have a successful pregnancy?

Thank you in advance by a very worried and hormonal mum to be.
