I have the same thing and i'm 5 weeks and a couple days. I talked to my doctor about it because the same has been happining to me and he told me that it's normal to have a bit of a discharge and even a period for your first 2 months (especially if its your first pregnancy btw for me it is)... but then again it could be signs of a miscarriage, talk to your doctor about it.

Hi. I'm 5w4d and I had (WARNING: TMI) light pink spotting, yesterday, when I wiped. I put a pad on and I only got brownish stains. I didn't have anything yesterday evening or today. I have an u/s on 07/23 and we're praying it's not another CP. We had DET/IVF on 06/23.
