Yesterday I had some bleeding and mild cramping. Scared out of my mind I went to the ER. I have had 3 miscarriage so anytime I see blood I know it's not looking good for me. They ran blood test and did an u/s and it show that I'm a week further then I thought and the baby had a heart beat of 167 and was looking healthy. I have had nausea off and on. Has this happen to anyone before and still had a healthy pregnancy?
