Quick question about when you have sex!!!

Jennifer

According to my ovulation strips, my peak LH levels happened on the 15th of August. From what I know, once you hit peak levels that means you’ll be ovulating 12-36 hours after this. Today is the 17th. Does that mean I have a good chance to getting pregnant still if I have sex today? Or have I left it too late? (Husband was ill and we couldn’t try for the last two days 😢). Thank you!!
