Ectopic

If you’ve had an ectopic pregnancy could you share your experiences with me? I’m really scared that what’s going to happen to me. I found out I was pregnant on the 28th of dec.. I randomly took a test and got a very very dark positive which is super surprising Bc I just had a period dec 11th. It doesn’t seem possible to get a positive test that soon. Also I’ve heard shoulder pain could be a symptom, which I haven’t had bad shoulder pain but definitely a little pressure here and there.

Can’t go to doctors till Tuesday and I’m freaking out.
