that what I thought might be IB was in fact my period...it was spotty and it was very light, but all my tests are still coming up BFN's

I NEVER (not that I can remember had a period like this (most of the time it was only when I wiped and was mostly pink, with a few spots of bright red...barely anything on the pad) ...I mean I have started 2 days early before, but a few hours after spotting full flow comes on, it didn't this time!
I got a

on my Digi on April 5, so I O'd between then and April 7th. I am so lost & confused on some things! I noticed that my cervix is still very high, but I thought it was low during AF? Also, because I didn't have a normal AF (meaning no heavy flow) do I count Friday April 20th as day 1 since that is when the spotting started???
Also because my AF was so different when should I start testing for Ovulation?? I just bought a new box of Digital Ovulation tests,(Just got my IC pregnancy tests in mail today...I got 100 of them for $12.99..so I am stocked up on them..

and I have IC OPK's as well! I just don't want to miss my surge!!
I just want my BFP!!!!
