I've been planning to take my son back home to see my family this weekend and a few days of next week. It's the county fair back home (call me a hick, that's fine

) and my little brother is bringing cows and it's a big deal for my family. DH will be staying home so he doesn't have to use up vacation time.
Sooo...I will be coming home to DH on CD 14. I have charted 7 cycles since my first post-partum AF and I have never O'd before CD18. I charted 2 cycles before getting pregnant with our son and I O'd on CD17 and 18. I didn't chart before that but based on my cycle length I think I have always O'd about then. I should be fine in getting back on CD14, right? I can just see my body randomly deciding to O early while I am gone and then we will have NO chance this cycle.
