Confused,.

I'm so confused about my cycle now, not sure when AF should know, when i O'd or what now

I know I took last active pill of BC on 12/11, last inactive pill on 12/18, but thats about it.

12/13/10 -- No blood at all
12/15/10 -- Spotting and clots, possible flow?
12/16/10 -- Flow regular
12/19/10 -- Flow over, infection back
12/27/10 -- Infection clearing up, feeling like a snail
12/29/10 -- Infection Gone, alot of clear discharge
12/30/10 -- Successful BD and alot of discharge
01/01/11 -- Infection possibly back
01/02/11 -- Throwing up at work, possible preggo?
01/03/11 -- BFN (Mid-Afternoon)
01/05/11 -- BFN (11-midnight)
