Hcg levels

Hey all! I have no clue where to post this so......here I am. I am 6 weeks pregnant. (Disclaimer: this is my 6th pregnancy. I have two beautiful boys.) Whenever I believe I’m pregnant I go and get my levels checked. Here they are:

1/3 361

1/8 3105

1/11 3543

I’m getting a little nervous. That last one didn’t double. And I’ve never had this happen before. It was doubling then slowed. I go for my next draw today. Anyone had a similar experience??? I will take positives and negatives. Just trying to gain focus on what could happen next.

Update: My levels went up again on 1/13: 4855. Still not a double. Waiting to hear from the doctor about next steps.
