so confused!

Erin

this is my 1st month ttc #3. i have always had regular 28 day cycles. af was due today. tues night i had some pink spotting. wed cramps and more spotting. i thought af was just coming early. then yesterday and today nothing. took more tests then i care to admit and they are all negative. What is going on in there? im still hopeful i may may get a bfp but also concerned because if not what is going on with my cycle and will it affect our chances this month. grrr.
