Tmi period pics!

Michaela trying for baby number #3

Hi I wouldn't normally post this here but need advice, I had this yesterday and the odd thing is I actually felt it sliding out which never happens when iv had a clot before but iv never had one this big before! Anyone else had the same size clot? Is it normal? And my period this time is a little bit cramp too. Do I need to go Dr's? Thanx
