Positive Opk??

Yesenia • Engaged to the love of my life! Full time student and mother to an angel baby that will always hold a place in my heart, a beautiful 9 yr. Old daughter, and an awesome 11 yr. Old stepson!
Is this a positive opk I'm not quite sure I took it last night and should I start BD every other day from now or wait? According to glow I'm not supposed to ovulate until the 22 and according to Ovia it's the 20th. Any comments would help thank you in advance :)
