HCG levels rise & drop

Michelle • 31 yrs old 💜 2nd baby 🤰🏽 Mommy to my princess 👑 another due Nov’2020

My HCG levels 2 weeks ago 9 weeks pregnant 🤰 were at 90,000.

I am now 11 weeks pregnant & they are at 50,000.

It’s normal for them to go down a little in 2nd trimester but is that a normal or good amount?
