Mid cycle spotting?

Brandi-lea • Khaleesi-May Dizney Van Vliet - my precious daughter born on 23.6.15 👶🏼🌸
Hello ladies- today I'm cd17 and I either ovulated yesterday or I'm ovulating today, I had a very strong positive opk yesterday but am a bit confused now as i just went to the look (sorry for tmi) but I was spotting pink, it was like a really like pink/beige colour and there was about a teaspoon of it.. What could this mean? Never had spotting before apart from ib a few cycles back (chemical pregnancy) so I'm a bit confused especially as it's in the middle of my cycle , 
​Thank you in advance :)
