OPK question...again

Okay...I know all of these questions have been asked before but PLEASE just humor me.
#1
I am super psyched that AF finally arrived (never thought I would say that...TTC is CA-RAZY), but I have a question. I spotted for two days on and off before she made her BIG appearance this morning...SO...do I count today as CD1 or Saturday as CD1? I know there are two different schools of thought and I just want to see what the majority is.
#2
last month was our first cycle TTC and I wound up having a either a 34 or 36 day cycle (based on the answer to #1) soo...when should I start testing on the OPK? Should I just do the whole test starting on day 10 thing and then go from there...
#3
is it really worth all the money to get the digital OPK's instead of using the wondfo strips? Are they really hard to decipher?

I am so sorry to bombard everyone on a Monday morning. TIA

Re: OPK question...again

IMO I would count today as CD1. Is your cycle irregular and all over the place? If so better to start early than late and take a chance of missing it. I have never used those tests, but I have used the lines OPK and they make me crazy. Way to much to decipher. I switched over to the smiley and am so much more relaxed using them. Good luck!
