confuse and stressing out

its took 7 years to have my first child. I never thought about having more. I wanted a baby girl and to my surprise I got her. I'm happy to have her in my life but lately family and husband corner me in having a 2nd child, I know they are a blessing yet i dont know if I want to, my first pregnancy was horrible I was sick all 9 month ,and at the time I had to deliver was worst I have to have immediate c section. I didnt have anyone on my side for support only my husband but since he work he wasnt much home. at first I agree to have a 2nd child but, I haven't been able to get pregnant. which is stressin me out, and debating to have another one. I guess I need someone talk to since where I live I have no family, and I don't know anyone who I can talk to about this
