My second delivery was on 8th May 2021.I didn't get my periods after delivery.Is it normal??I did sterilisation. I am breastfeeding. I am taking medicines for thyroid(25 mg).My TSH is 3.5.

A. after delivery no period yet.. it depends on one to one as some gets very next month and some may get after one year of delivery my period started after 4 months of first delivery and after eight months of second delivery
