So I'm guessing this will be solved very quickly (most likely with full arrival of period)
History:
Just shy of 2 years to conceive Dd. Conceived 1st try after lap&dye.
Cycles were irregular until pregnancy. Daughter now 1, periods returned at 4mknths even though ebf. Starting to go slightly irregular again but only by 1 day.
Today:
Trying for Baby no 2. Period due Wed. A little bright pink spotting yesterday followed by dark brown spotting and tiny clot like things. Not enough to fill a pad all day. 11dpo today.
So is it beginning of irregular periods again or implantation bleeding - who knows! Eh!! Just needed to chat about it and ponder.
Slightly crampy and tender nipples- which was sign of 1st pregnancy but also sign of my period 
who has a magic ball!?
