How far away would he be traveling? Would it be possible for you to meet up at some point during the week if you needed to? I'm sure your students wouldn't mind if you canceled class at some point to travel with him, either! :)
Hi, just wanted to chime in. My husband travels for business as well and when we first started to TTC I was concerned we would miss "the O window." But in the first whole year, we never missed a cycle. It always seemed to fall over a weekend!
Of course, with the whole azoo situation we're in, it didn't matter. But that's part of the reason I *knew* something was wrong - we had always had fantastic timing!
Hope you have better luck!
Unfortunately, I don't have a positive experience with this.
If it helps at all for your peace of mind, this baby was concieved DTD 4.5 days before the O day (according to FF)... Oh! and it was our first try!!
I would try to relax as much as possible. Just make sure you have sex on monday so you have the week as covered as possible. It is totally possible to get pregnant that way!
