HCG levels

Abigail • Pregnant after chemical in December/January. So excited 👶💜
Hello ladies just wanted to share my HCG levels with you because I'm a bit concerned about them 😖 I got my first HCG levels late Wednesday night (4th-11:30pm) and they were 533.6. Got my next one Friday morning (6th-10:30) 843. Then the third on Tuesday (10th-11-11:30am) and only 2,332?!?! I thought they were supposed to double every 48 hours?!
