Ectopic pregnancy HCG from 200+ to 100+ in a week is normal. Ectopic pregnancy, customarily known as ectopic pregnancy, is a condition in which a fertilized egg is deposited outside the body cavity of the uterus, with tubal pregnancies being the most common. Ectopic pregnancy treatment options include surgery, medication and expectant treatment. Regardless of the treatment option, the blood HCG drop needs to be monitored weekly after treatment until normal levels are achieved. Normal blood HCG should fall to less than 50% of preoperative levels 1 day after surgery and less than 10% of preoperative levels 12 days after surgery. The decline in blood HCG should be >15% 4-7 days after conservative drug therapy. If the test blood HCG does not fall or falls but rises again, it is necessary to go to the hospital in time to clarify the cause.
