I think everyone is scared of labor! It isn't a fun thing, and it hurts a lot! But it's worth it in the end, talk to your doc about your fears with your doc.
If its really risky, n u hav bad gut feeling bout Labour, I say u talk to ur doc n mayb do n elective c section.. Pacemaker is a big deal, n since u r already 37wks, u can talk to ur doc bout it.. Healthy baby n mom r most imp than natural birth or c section!!
