Ovulation advice.. TMI!

Hey ladies, so AF was the 4-9 of June. I had EWCM on the 13th and glow says that my fertile window was the 14-19(with the 17 being most fertile). I had medium creamy CM on the 17 and medium watery the 18. On the 20 I had very light pink spotting when i wiped(not enough to get on my underwear tho.. Sorry tmi). I've been cramping the last few days.. AF not due until 7/2. Do you guys have any idea how many DPO I am ? I haven't used opks or taken bbt so I am unsure and would like some input. Thank you!
