Well, I had a dr.'s appt. on Tuesday and he ordered another ultrasound so he could check on the placenta previa. The ultrasound was done on Wednesday as well as a Non-Stress Test. The placenta is completely blocking the cervix and the amniotic fluid is low. So I've been put on bed rest. He also ordered me to come in twice a week for Non-Stress Tests. I have one scheduled for tomorrow. He scheduled another ultrasound for next Wednesday as well as another NST. Needless to say, not a whole of school got done this week.
The girls carried on somewhat with their independent seatwork (MUS, ETC, & handwriting), but I did not do any read-alouds or any individual lessons with them. They have been helping me with the housework, cooking, taking care of the toddler, etc. so I have let them have plenty of free time to play outside (the weather's been nice!).
I think it would be nice if I had kept up at least one read-aloud but I just haven't felt up to even that this week. Thankfully, the girls have spent plenty of time doing free reading of their own. They've also done their Picture Study and Folk Song for this week. And they've played educational computer games and watched videos. And dd10 has kept up with her AO Year 4 readings. She did that all on her own. She got my binder out, looked up her reading assignments, and did them w/o me telling her to! All in all, I think they've done enough “academics” for the week to still count this as a school week. It's been more of an unschooling week, but at least I know their little brains are still being stimulated. 
Oh, by the way, ds is supposed to get his stitches out tomorrow!
