HCG levels?

katie

I’m currently 4 weeks and 4 days. I’ve had my HCG levels drawn three times so far. I heard they need to double ever 48 hours. From my first test to the second they more than doubled but from my second to my third they only went up 59%. Has anyone experienced this and is this a cause for concern?

Test 1 at 4 weeks: 194

Test 2 at 4 weeks 2 days: 499.1

Test 3 at 4 weeks 4 days: 797.9

UPDATE!! My last HCG test went from 797 up to 2,100!!✨ next up is the first ultrasound!
