Do I️ still have a chance this month?

So this month my husband and I️ regularly

BD’d every other day since the day after my period however we had to stop on Sunday due to him traveling. We did BD on Sunday but I️ did not get a positive opk until this morning (Tuesday). Since my last time was on Sunday and I️ didn’t get an opk until 2 days later, do you still think I️ could have a chance this month? Or am I️ probably out? Of course he will be back right after my fertile window ends on Thursday, ugh.
