Your first beta hCG is 100.
Two days later, it’s 150.
It rose—but it didn’t double. Does that mean the pregnancy is ending?
Not necessarily.
The belief that hCG must double every 48 hours is one of the most persistent myths in early pregnancy. The expected rise depends partly on the starting value, and some IVF pregnancies that resulted in live births had rises much slower than traditional rules suggest.
In this week’s episode of Taco Bout Fertility Tuesday, we discuss:
✅ How quickly hCG really needs to rise
✅ Why “doubling” is not a requirement
✅ What a slow rise may mean
✅ Why even a perfect rise cannot rule out an ectopic pregnancy
✅ When symptoms matter more than the numbers
