Hi everyone, girls. I'm breastfeeding. I had an ultrasound on 24/12, and they measured an endometrial thickness of 9 mm. Ovulation should come soon, and I'll be waiting for my next period in January. For several days there's been some spotting, a drop here and there, two days of red blood, like the start of a period, but it hasn't progressed. I don't understand what happened. Or is this just a breastfeeding-related quirk? Then I might as well just keep breastfeeding the older child and that's it... Pap smears and cytology were normal; we all had them after the lochia. I haven't lived half my life yet.
