Advice please!

I had a positive pregnancy test last Wednesday. I have irregular periods and been on the mini pill for two years. I stopped the pill at the end of August. I think I ovulated 9/13 or 9/14 but I’m not certain.

I had blood work done to check my HCG just to be sure, and it came back 25. I repeated my blood work this morning, and they added progesterone too.

Any thoughts on how far along I am? I know they usually count from the last day of your period, but I haven’t had one 😖

I’m anxious about my labs. Praying the numbers are going up!
