My dd is now 3 but since having her my periods have been very different. They're not at all regular and can start very lightly and then almost dissappear again, only to come on again quite heavy. Is this normal? It can be quite frustrating as they're difficult to keep track of when they're like this. So I never know when to chart my first day of actual bleeding. Have also been having anxiety /depression with pmt on some months and not others. Just want to know if this sounds normal or if I should go to the doctors?
