Weird bleeding

hi everyone,

this might be absolutely too much info about to be written here but going to ask anyway. I already have 2 children. Hubby and I decided to try for a third so I've stopped taking the pill midpack (I know I shouldntve) 

i had my regular bleed between the 7th and 12th of this month a little heavy but nothing really to worry about. my cycle was fine and I stopped taking the pill on the 18th - I started my withdrawal bleed yesterday a little light spotting exactly what I would expect being that I've been in this situation before when I fell pregnant with my daughter. This morning I have very very heavy flooding And some light cramping. It looks like Po bleeding and I don't know why. Anyone who can shed some light?
