Still a chance?

Kristen • Mom of three, 13 year old son, 4 year old and 2 year old daughters!
I got a strong postive opk last night around 7 PM. My husband basically refused to have sex because he's on third shift and trying to stay up and it puts him to sleep lol. We had sex the night before (Sunday) and will again tonight. Do you think I still have a chance or did I miss it? Here are last nights with one from this morning on the bottom. What do you guys think?
