Spotting

Is brown spotting normal during early pregnancy ?

I’m gonna be 5 weeks tomorrow and I’m spotting some brown discharge today

Yesterday I had cramps but I’ve had cramps since I found out

I’m not seeing an ob gyn yet because I’m waiting on my insurance to get approved I’m freaking out I have 3 kids and this didn’t happen with any of them

Idk if I should go to ER cause if I went you can’t see anything in ultrasound yet anyway

Could this also be a symptom of an ectopic pregnancy ?
