Is it normal that my hCG is dropping at 12 weeks

A: What you describe is completely normal. The hCG normally drops after 10-11 weeks of your pregnancy. The doubling of the HCG only applies to an early pregnancy, up to an hCG of about 6,000. After that, the hCG rises much slower, and at 10-11 weeks it normally drops. A good fetal heartbeat after 6-7 weeks is the best indication that the fetus is doing well and there is no more need to do the hCG after that time.
