I never wanted to use the pill while breastfeeding - we used condoms for 14 months while breastfeeding. We never DTD without protection as too many of my friends have fallen pregnant while breastfeeding to take the risk.

I still had lochia bleeding for 5 weeks so it could be the end of that. If you are feeding more than 5 times in a 24 hour period then it is unlikely you would become pregnant but yeah test again in a week just to put your mind at rest!
