Panicking

Hi

I'm 10 weeks 4 days with my first baby. Been married for 2 years. Had been trying for 6 months . Been so happy and excited until now. Starting to feel suffocated. Panicking that I don't know if I do want to have baby or not. Was 100 % sure until now. Starting to panic about my relationship. What's going through my head right now is for me to move out and get some space from everything for few weeks so I can think about what I really want . Help why am I feeling like this
