High hcg/beta

Ebony

So went in to get my hcg checked by blood drawn and it was 850 at just 4 weeks moving forward to Tuesday 4weeks 3 days I got more blood drawn to check hcg and it jumped to 4457. They want me to come back again on Thursday to get more blood drawn , I thought they only drew blood to make sure it’s going up and mine is definitely going up quickly which is a blessing but I’m just wondering why they keep checking my hcg if it’s going up rapidly ? That’s usually a good thing right ? just would like to hear if other ladies had high hcg while pregnant and what your experience was like, I feel like it’ll be a nice conversation while awaiting my next doctor appointment. Also don’t say anything about a molar pregnancy lol keep that mess on google ….
