HCG LEVEL QUESTION! So confused 🤷🏽‍♀️

OK ladies we’ve all heard that an initial HCG # doesn’t matter and that what matters is that it doubles. We’ve also heard that some women have high numbers and others have low numbers and every body is different..

But,

The doctor I saw today said it’s not possible to see anything on ultrasound until your levels are at least 1500.

So we can both be 6 weeks (for example,) something will show on your ultrasound cuz your level is 1500 but nothing on mine cuz mines at 750 and that’s supposed to be ok???????????? I’m not supposed to be concerned about that? I have to wait longer to have a yolk sack and embryo but I’m supposed to believe my pregnancy is progressing as it should? Like how does that make any sense. Asking honestly

I would have asked the doc but I didn’t think about this til I was in the car 😩🙄
