From 8-10pm I was having uterine tightening every 5-10 minutes. They continued more spaced out throughout the night. I have been drinking a lot of water and emptying my bladder to help. My doctor wants me to come in at 10:30 central time for an ultrasound. Prayers would be appreciated. I am hoping that it is nothing, and just another blip on this road to beat infertility.
