Has anyone had low hcg and not had it turn out to be ectopic. I’m extremely nervous this is a ectopic pregnancy. I went in for a draw today to see if it doubled since it did start increasing normally. Mommy gut is telling me this is not viable but I fear ectopic. She’ll do an ultrasound if it doesn’t double.
