I’m six weeks pregnant and today when I wiped after going to the toilet there was some unusual pink/brown coloured discharge. I'm worried about it.
This is actually perfectly normal at this stage of pregnancy as t's most likely just old blood, and you will have an increase of blood down there now anyway. It can also happen if your cervix is irritated by having sex.
If you're really concerned or it happens again, I would advise to go to the doctor's just to be safe.
