I had a baby almost 16 months ago. I have just recently started having my period again. I'm having them every 2-2.5 weeks now. The one I'm currently having is extremely heavy! The clots are huge. A few questions... Is this normal after a baby for it to take a while to get back to normal, should I be concerned with the huge clots, us there a way I can send the clots to a phd to get them to look/test to make sure it's OK
