Coming off BC...

ashleen
I was on BC for about 6 years. My husband and i are now ttc baby #1 so i came off BC in may. I had a normal cycle in june and exoected my next cycle to start on tuesday but there is still no sign of it. Before bc and during my period was predictable to the day and very rarely was off. I am now 5 days past due and 2 BFN tests... what could be going on?!?
