Hello ladies. Pregnancies are different for everyone as our deliveries and the way our bodies react after delivery. What you are experiencing is not unusual nor it is harmful in most cases unless and if the bleeding continues for a long period of time which means you could be hemorrhaging. Before you become very frustrated to give it the normal length of time for your usual period to last. If the flow does not lighten and the cramps don't stop or if at any time it worsens contact your doctor immediately, it could mean that all of the placentae did not drop or something simpler like your body trying to rid itself of the extra blood that has accumulated, remember you haven't had a period for 9 months. Whatever the case after a week or if it would make you feel better to check sooner you should find out if there is something out of the ordinary going on with your body. It is never wrong to be safe rather than sorry. If you feel uncomfortable to the point that you don't want to wait then see your doctor now.Good luck.
