"rest"

So, for the past few days, I've had some minor scares each day, whether it be spotting, lightheadedness or weird cramping. Nonetheless, it's a bit worrisome. I went in for a last-minute appointment and everything checked out ok. They're doing some tests that I'll get results back in a few days, but the doc didn't seem too concerned.
[Side note: I saw a new doc for our practice and she's fantastic--so much better than my last experience there!]
She told me that I need to "rest" for the next week or so due to all my varied symptoms. All I've done this past week is 1 hour of prenatal yoga (in which we took it easy since I'm the only person in the class and the instructor has been tailoring it for me). Bummer--with all of the weight I'm gaining, I was hoping at least to do some minor walking, but oh well. It's all for the baby and it's health. If I need to rest and lay on the couch when I'm not at work, I'll do it =)
