Hi mom it's perfectly normal Period usually don't come as long as you breastfeed your baby.after my 1st pregnancy my period had come after almost 2 years☺n in second baby it started after 9 months only so nothing is wrong..for headache your lack of sleep may be the cause try to cover your sleeping hours whenever possible.

Yes it is, if you are exclusively breastfeeding your baby. I did not have periods for almost a year as I was breastfeeding and my doctor said it's perfectly normal.
