I need help ladies

I always used opk 7 years later still no pregnancy this month I said fuck it I'm tired of wasting my money but I actually regret it now because I am so confused lol....

I usually get a positive opk on cycle day 13 and yesterday was cycle day 13 for me I also had egg white cm with spotting along with cramping and ache ovaries around 10:00pm we also baby dance in the am so the spotting could be from that but I usually never spot after sex

My question is when should I start counting dpo today or tomorrow??

I bought a pineapple but I need to start eating the core during 1 - 5 dpo....
