Scared of pregnancy

So my boyfriend and I have decided we want to start trying for a baby. A little problem though is I’m very scared of child birth and the check ups. I have a very very low pain tolerance (I actually cry when I get the flu shot) I’m so scared of childbirth and the blood tests ( the last time I had a blood test I threw up fainted and they had to lay me down and switch arms). I truly do wanna be a mother some day very soon would be wonderful I love children and it’s always been a dream of mine to have my own. I was just wondering how bad is childbirth really (in general I know it varies)? And how often do they do things like take blood? Also does it hurt at all after is there anyway to ease the pain of childbirth???
