Fertile window

My fertile window was this week. My hubby and I bded on the 24th but he didn't get off (he had a couple drinks at family Christmas) I had ewcm yesterday.. We don't bd a whole lot, dr scheduled to try to figure it all out (so we didn't last night) I know that men have precum.. Could that possibly give me the tiniest chance to conceive this month? We have been trying for #2 for over a year. Keeping my fingers crossed that it somehow happens!
