Hello girls! I have such a problem... I did two tests, one in the evening and one in the morning Both were positive (for pregnancy) I went for an ultrasound, they checked and said it's early, there is nothing yet in my uterus and it's not visible But I am breastfeeding and continued And yesterday evening I was sitting and suddenly blood came out and stopped immediately, and so on this morning but already brown, and it hurts my waist What should I do ?? It hasn't been a week yet that I would go back to the ultrasound doctor.
