I hope it is appropriate to post in this section, and I apologize if I am making a mistake.
My baby girl is 3.5 months old and fully breastfed since she was born. We never had any problems and she gained on average 250 grams per week. She eats every 3/4 hours even at night, I carry her around with a sling most of the time, we co-sleep, and I am not giving her any other food beside my milk. So why this morning I got my period? I am not worried of having my period, but I am afraid that this will diminish my milk supply. Anyone else had a similar experience?
