Early pregnancy anxiety

How do you deal with the overwhelming concern and anxiety of the first trimester?

This is my second pregnancy and I have a beautiful 7 year old daughter. And I’m 5 weeks pregnant now.

I found out at 5 weeks with my daughter as well. I was very sick during my first pregnancy but never any severe complications.

And I’m in better health then the first time, besides being overweight.

I’m trying very hard to stay positive and healthy, but so overwhelmed and concerned with what if’s.

How do you deal with ? Does anyone else experience this or am I just crazy?
