I had my baby 8 weeks ago and bled after birth for 5 wksish and we started having sex around 4 wks after. We have been careful only one night the condom came off (but we stopped straight away) and another we used the withdrawal method. Anyway I had some brownish blood (hardly any tho) on weds and thought it was my period beginning but it didn't start as i'd expected and then the next day I had the same but a little lighter and its now three ays on and no period. Is this normal after birth? It would be my first period if it is possible for it to be so light, i'm slightly worried its an implantation bleed. Anyone any experience of this? Could I be pregnant so quickly again?? Please help.
