I had the same thing.. it was a harmless clot in my uterus that bled. It went away by 16 weeks.
I talked to the nurse and she said its normal but Im still worried
light orange discharge now, but at 7 weeks i had some spotting for a day or two and then it was fine, if im dehydrated after i go to the bathroom and whipe it looks orange a lil but other than that nothing just keep an eye on it if it gets worse or bothersome ive a call to your ob or midwife.
