5w5d ultrasound and saw nothing HELP

Mrs❤️

So I went yesterday for my first ultrasound.. according to my lmp on 9/24 I should be 5w5d but dr didn’t see even a sac on my uterus at all, and started saying it’s most likely ectopic.. my levels more than doubled on my last scan and were 1165 2 days before the ultrasound.. should I be worried? She wants to recheck levels tomorrow but was talking about doing a d&c Wednesday if my levels are dropping.. could it just be too early to see anything? Please help!!! I’m so scared to lose this baby!!
