R.S.
I am trying to think back when I was in your shoes. I had 5 miscarriages in a row...so it almost became where I was no longer anxious I just expected to lose the baby. When I actually got past 12 weeks, I was losing them right around 10 to 11 weeks along, That was when I started feeling anxious because I had never carried that far before.
What I did was tell myself there is no way that I could do anything that would make myself miscarriage...either I would go to term or not, but my body was in control and beyond that God was in control. I gave the situation over to God.
It turned out that I had a medical problem that was causing my miscarriages and once it was fixed...I had my son. Then I had another miscarriage between my son and daughter.
Only one of my babies had a genetic issue incompatible with life Triasomy 16 or was it 13...that one would not have made it no matter what...but all the others tested normal.
Just try and relax and know it is out of your hands...and there is nothing that you can do or not do to cause you to miscarriage. It isn't your fault. Try and enjoy your pregnancy as much as you can.
