Ectopic?

L

Anyone have an ectopic pregnancy? I found out I’m pregnant this past Saturday but have had red bleeding since then on and off. I called the doctors office and told them this and all they are doing to start is to check my hcg level. Should I be concerned about ectopic? When does that become dangerous? I’m 4 weeks 3 days.

I keep taking pregnancy tests and the lines are getting darker but I did read that can keep happening with ectopic or miscarriage too.
