From looking at your chart I'm guessing you are just incredibly early in getting blood work done. Are your doctors sending you back for more bloodwork to check for doubling time? That's really all that matters. GL and FX for you!
I'm in a similar boat hun. My first beta today was 23...I'm terrified of that number not doubling for my next beta. So many women on here have given me hope though, and I'll know they'll do the same for you. I'll be keeping you in my thoughts! XO!
DS was a 12! My hpt showed the faintest line and DH thought I was crazy. Because my first pregnancy was ectopic, I called my doc and got the bloodwork that day. Based on my due date, we were pretty sure that I ovulated a week late so we were all surprised by that first number but 24 hours later it was a 72. Many wonderful wishes to you.
Re: HCG of 7...

No worries! They just caught you eearly on! It is possible! and does not mean ANYTHING is wrong

at 6dp5dt or 11dpo my DD's hcg was 17. She worked out just fine.
And the day before i was getting positives on a digital test. Man those things are sensitive!
It's not where you start it's how it grows!

My first beta was 18 with DD1, and my RE was shocked that she was a sticky bean.
You are just super early. I'm sure your second numbers will blow your socks off.
