I have never had to deal with this, but, it sounds to me like you body may be telling you something. It might be exhausted after everything it went through and just need a break. I have found, from girlfiends trying, that if you just relax and not worry too much about it, then it will happen. Your body may have some "repairing" to do before it is ready for another baby, and for the baby to be healthy. Good luck
