New mom to be here, and I’m feeling scared and nervous!

I went to my first ultrasound thinking I was closer to 6 weeks; however, when I got there my ultrasound reflected 4-5 weeks (so not much at all could be seen) and my blood work displayed an HCG of 712 and progesterone of 29.80. I have irregular periods, and don’t track them. I believe my last period was the last week of December or the very first weekend of January. I tested positive February 4 for the first time and have continued to test positive.

The doctor didn’t seem to concerned, just seemed to think it’s too early and ordered for follow up ultra sound and blood work 10 days later.

I’m ANXIOUS. I’m going to call tomorrow and request the blood work sooner to helpfully help calm my nerves but does anyone have any advice or recommendations? Based on my situation, what do you think? Anything similar? Is it possible for me to be 4-5 weeks pregnant on February 9? I would call my doctor today but she’s out of the office!
