i started a new birth control pill about a month ago. when i first started the new pack on the day/first few days of my period, my period lasted a bit over 2 weeks (my period usually lasts 4-6 days on the old birth control). It’s been about 24 days since my last period and my new birth control that i started l around the same time. i finished the pack about a week and some days ago and my period still hasn’t started. i’ve also only had sex twice since my last period and both times i made sure to wear condoms. is this normal? should i be worried?
