Oh honey i am so sorry for your loss. To me it sounds like it is the start of your period. Your period will return when your hormone levels are back to normal. Your levels were probably dropping for the last few weeks of your pregnancy so one week after a D & C could be right for sure. In saying that i did fall pregnany quickly after my 2nd D & C after my 1st lost but my hormone levels would have been very low for a while as there was a gap between both D&C if that makes sense!
