Girls, has anyone experienced this, I haven't yet, yesterday I took a test, 2 bright stripes, went to the doctor, in the pregnancy she doesn't see anything, but sees fluid behind the uterus if I understand correctly, says the assumption that it is an ectopic pregnancy. There are no symptoms, only pressure in the lower abdomen, constant urge as if to go to the toilet, big Has anyone had this before, and everything turned out well at the end? Said to come back next week, the doctor is the best, experienced, doubts about his qualifications don't exist, two of them he gave birth to ?
