Nervous after miscarriage

We recently had the heartbreaking experience of going through a miscarriage. It has made Christmas tough as we had planned to tell everyone on Christmas Day with gifts. It's so hard not to resent people sharing their happy news just now. I know I am very lucky as I have a son from a previous relationship as does my husband but we would love to have a baby together. Now I'm petrified it will happen again, I don't think I'm strong enough to lose another baby. The midwives have explained that the chances are low but I'm going to be a wreck waiting to check everything is ok. Need to pull myself together and get on with it I guess.
