Positive OPK? Newbie!!

Samantha • TTC #2 since Feb 14.
Haven't used GLOW for ages as I didn't have a period for months! Then over a week ago I had a little bleeding and thought "what the heck! Let's give this another go!" This morning.. 
​Just did this opk at 7:30am and I think it's positive!?
​Hubby & I BD's last night.. Not sure if that has any effect lol?? HELP!!
