I understand why you would be worried about your supply after having all that going on. It sounds like you had a pretty difficult time of it.

It is hard to know whether those signs all together meant your supply was low. However the fact that you did bf your DD for so long and she did put on weight suggest that you did have enough milk. Usually the best ways to tell that your baby is getting enough is from their nappies, at least 5 heavily wet disposables in 24 hours, soft poos, and at more than one a day in the beginning, also that your baby is gaining weight over time, and seems healthy - alert and settled at least some of the time and good skin tone, bright eyes.

Have you considered doing a Breastfeeding Education Class before your new arrival? The information at these sessions is fantastic and this will also give you the opportunity to meet local counsellors who will be able to assist you with information and support after the birth if you need it.
