Fertile window

Jackie
Hey everyone 
I need your advice. My ovulation window started on the 24th and ended today. My two most fertile days were the 27-28. Hubby and I have been extremely busy and only were able to BD on the 17, 22-23 and 26th. Do you think we have a chance of conceiving this month. I took another opk test alittle while ago and It was as dark as the other day. Hopefully we can try again tonight. Fingers crossed for our rainbow baby.
