A week ago my doctor discovered that I have a genetic mutation and advised me to taie livanix shots to prevent any possible harm to the baby. I understand that blood clots could cause serious problems to the baby, so I'm overcoming my fear of needles and giving myself shots in the legs every morning. Does anyone else go through this? I've had a miscarriage 4 months ago and my doctor thinks this might be the reason. I just want to know if anyone experienced anything like this.
