Hi, i had my baby nearly 8 weeks ago and my pregnancy books tells me i should have my periods back by about 4 to 6 weeks, mine have not returned yet, yesterday i went to the loo and when i wiped i noticed watery blood on the paper so i assumed my periods had started but that was it ive had nothing else since then, not even when i go to the loo there isnt nothing on the paper its compleatly gone, is that normal and is it normal for them not to have started yet
