###Human: Why is the hCG not raising although the endometrium is thick? ###Assistant: Hi. I have read a detailed description of your query. Beta hCG should increase around 66 % after every 48 hours in a normal healthy pregnancy. Have a strict check on your symptoms. Beta hCG if shows increase but less then 60 %, then ectopic should be excluded by having transvaginal scan and symptoms. In case of a suboptimal increase in beta hCG, actually happens in pregnancy outside the uterus. In your case, beta hCG is very less, not even above 500 and should be followed strictly. Symptoms could be abdominal pain, bleeding, etc. It is better to repeat beta hCG after 48 hours and have a detailed scan with expertise hands. Follow beta hCG scan, check in detail and report symptoms that you have to an emergency gynecologist. Ectopic. Beta hCG, a detailed transvaginal scan. Ectopic, early pregnancy. Have beta hCG and detailed expertise scan with a local examination. Strict check on symptoms and report.
