Go to the gyno and let them know. Might be a hormonal issue. Before pregnancy, my period lasted 3 days (1 day being the heaviest). Then after birth, my flow was sooooo heavy for 2 weeks, and they started lasting for 2 weeks every month. I told my gyno and i got ultrasound and they saw a cyst. So i got on birth control and its much smaller now and my flow is back to normal (3-4 days).
@Aolani thank you for this!!! I am going to book because this is not normal! Glad you got it sorted and are doing much better!
How heavy*
