Okay Ladies I need some help. I've become a POAS addict and to try and calm myself down I decided to use some opk sticks instead. I'm currently 4 days away from glows predicted start of my period. Is it normal for an OPK to look like this?

I've never used an OPK stick after I've had a positive. I got my postive OPK stick for this cycle on CD 15, this was May 28th so I'm assuming I ovulated on May 29th... This month for whatever reason I have been convinced that I am pregnant! I'm starting to stress now that this isn't my month and that the OPK stick is signaling my period is coming? Please help me understand what is going on ladies.
