Gave birth 12 weeks ago and got my first period 9 or 10 days ago, it started off light with old looking bloody but after 4 days got heavy and bright red now it's soaking a pad in a few hours and i started getting small clots with slight cramps for the last few days. I just went to the loo and had a big clot about palm sized it was rubbery and looked similar to the mucus plug is this normal? It seems to just be getting heavier and heavier
