I did take Yaz, I hated it, it did weird things to my body. My gyno said it is the ONLY pill that gets complaints from women who say they feel crazy. It is uniphase, meaning that in each active pill there are the same amount of hormones. I couldn't bring myself to stay on it for more than three weeks.
After a while off BC, I asked for a different kind of pill because of menstrual issues (my boyfriend is deployed and leave is a LONG way off.) I was given a different low-dose that is tri-phase and I have had minimal problems and much better menstrual symptoms. I'm only two months into it, but that's a pretty good sign!
I would say keep taking it for the whole month. I don't know how long your husband's deployment is, but I sure wouldn't want to go through a pregnancy alone ... and wouldn't want to go through his leave without COPIOUS amounts of sex

Stick it out while he's home and then see your doc.
