Afraid to be happy

LP

When I first found out I was pregnant it was a suspected ectopic. Turns out they were wrong but I have so much anxiety that I haven’t been able to relax and enjoy the fact that I may be a mother. I think it won’t hit me until the baby is 3 months. I will be 15 weeks Wednesday. Am I the only one worried something will happen ? My SO thinks I’m being negative, but I’m just too concerned to be able to enjoy this.
