Help! Did i miss my window??

Haley • 31. Preggo with baby #2 ❤️ first boy 1/09/20

So i got a positive OPK at about 4pm on Saturday. We had two pipes burst in our home due to the freezing cold to warm temps and it just wasn’t in the cards for BD. We BD’d last night right before bed. Do you think i missed my window from not having sex Saturday??
