Positive opk?

Question

opk?" /> Okay ladies so here's the deal my period is due in 3 days  I have been doing opk all month have yet to get a positive which  worried me bc I was on oral birth control for 8 years , off for only 4 months ttc with no luck. Even though my period is due in 3 days I figured I'd still check. So my question is , is this a positive opk and is it really possible to ovulate this close to my period? Thanks
