I have the exact same problem, it's only when I wipe and yesterday it was like a lightish browny colour, yet tonight its a pinky colour, i'm 7 weeks pregnant and nervous as hell about it because of what I think it might be, but i'm going to the doctors tomorrow morning sometime to find out exactly whats going on.. I hope its not what I think, my mum thinks it's nothing and she said it could just be left over from a period, but my last one was in december, so I dont know.. Meh.. I'm nervous and scared and worried, mum thinks im stressed over nothing and everything is okay but I still just need to know.
Wish me luck. :cry:
