Girls, hello everyone. 6 weeks pregnant, I haven't had an ultrasound yet. But I'm very afraid of ectopic pregnancy (as my friend had surgery because of this. There are no symptoms, discharge is normal as before, it comes and goes. I only feel pain in my lower abdomen sometimes. And not even that much. Do you think I should wait until 8-9 weeks, or go for a check-up?
