Girls are panicking a bit, can you tell me if I should see a doctor or call an ambulance? Today after daytime sleep, there were discharge with blood mixed in, maybe 2-3 drops, at the end of my 8th week, I didn't call an ambulance, left the senior one alone. Now it's been a couple of hours and it seems okay, just a slight pulling sensation in the abdomen and lower back, so I'm thinking what to do? Or can I wait until Monday and go for a private ultrasound?
