My hcg levels are rising, my first one was 214 four days later it was 411 four days later it was 797 a week later they were 2113.5. When I looked on line I saw they were supposed to double every 48 hours, also I'm supposedly 6 -7 weeks along. This is my fifth baby and I'm not having any of my normal symptoms, like nausea and vomiting. My worries are that my hcg levels are low for my weeks. Along with no real symptoms. I'm so stressed out.....can anyone relate???? No bleeding, no strong cramping, idk!!!!
