Need help

Ladies, I need an opinion since I don’t have much friends,

My lmp was June 4th, I wasn’t tracking ovulation days this time as I gave up after trying over a year and it never happening. I do have PCOS, and had some fertility treatments in the past to help with 1 pregnancy This time, I got pregnant on my own, no meds but I have no idea how many weeks I am

I tested july 18th, and negative

I tested july 23rd and got a faint positive test and on the 27th, my hcg level was 268 and then I had my blood retested again, August 5th, it was at 13,182

So my question is, should I schedule the ultrasound this following Friday or leave it at for next Monday. The reason, I did the next Monday first place is I didn’t want to go in too early and they don’t see anything. But after seeing my results on the 5th of August, I think it’s safe to say that I’m over 6 weeks based on the estimates of hcg levels.

What would you do ? Go in Friday or leave it for next Monday ?

Thank you ☺️
