1st Cycle off the Pill - into day 16 and AF already!?!

I have been having pains and bloating like AF and I thought that it was O because I was supposed to be in my Ovulation Window... then last night I had a bit of light blood when I wiped and again this morning but very very light (sorry TMI)
Im only in day 16 of my 1st cycle off the pill and I thought that this would be too short of a cycle to get AF already! I guess the whole coming off the pill thing is a big learning curve!
Feel a bit sad and I was hoping to concieve - I know that I prob wouldnt 1st cycle off the pill but I guess I had my hopes up!
Could there be another reason for light bleeding??
:(

you never know i fell pregnant first cycle after several years on the pill with DS..I cant believe how lucky I was now its taking much long with TTC #2.. everyone different. sending you baby dust!

Bleeding has kind of stopped - not really bood though - kind of light pink bits of stuff - I cant explain it but not like AF. Not sure what it was or is - guess I have to wait and see!!
