I have had hardly anything at all either. When i was 4 weeks i had a little constipation but that went after a few days.. other than that ive had nothing until this week when ive started some colostrum leaking but that only happens when i squeeze my nipple a little. I have the faintest of lines down my belly, if you could even call it that. I say its just a matter of everyones different. It doesnt mean the baby will be any better or worse off.. its just the way everyone's bodys react differently
