Low and slow rising HCG? Any success stories?

Leslie

Hello! Per my last cycle, my due date is October 3rs, so about 4 weeks, 5 days pregnant. The HCG tests began on cycle day 26/28, so I hadn't missed my period yet. Here are my hours for levels:

01/21 - 3

01/23 - 21

01/25 - 32

01/27 - 41

My doctor is scheduling a pelvic ultrasound to see implantation and location and I'm nervous. This is my first pregnancy. I've had cramps similar to menstrual but no bleeding.

Any low HCG success stories? Thank you!
