Positive OPK

Kaylie • I`m 25, I have a beautiful 4 year old, an infant, and two angels watching over us.
Ok, so I have been using the clear blue digital OPK and I had a low fertility test on the 8th 9th and 10th and I had a peak fertility test on the 11th and I couldn't test today because the stupid smiley face wouldn't go away from yesterday's test.... but anyways what are the chances I may have conceived? I had sex on the 9th a little after midnight (so idk if I should count that as the 10th?) And then we had sex again last night.
