I was of the understanding that periods would be delayed while breastfeeding. I had my DS 5 weeks ago and am breastfeeding exclusively for what seems to feel like constantly and I have my period. I will ring the midwife tomorrow but has anyone else experienced this? I am most disappointed to be in pain and grumpy when I thought I might get a reprieve even for a while. I know some people can be irregular later on but I have not heard of starting back so early.
