Were your hcg levels doubling in the beginning of an ectopic??

NS

I had 2 samples drawn 48 hours apart, numbers are somehow low but doubling.

2 Oct: 192

4 Oct: 476

I’m extremely worried, as my levels in my first pregnancy were way higher at this time. I feel something might be wrong.

If I go for an ultrasound now, will they be able to detect anything??
