So long story short i have a very irregular menstrual cycle and after months of trying my doctor saw something on my ultrasound and said he's hopeful and to wait a little longer to see if the little black circle grows I even had some of the symptoms, a week ago a dark brown discharge started and we thought it was implantation it was very light and almost over and today i sat on the toilet and dark red blood came out not a lot just enough to make a small circle and now it has stopped so I dont know what to think can anyone help please..
