Is this normal?

So for the past couple of days my knees have been giving out whenever I have been sitting down for a couple minutes or more and then go to stand up, and this morning I woke up to both my upper arms muscles sore and hurting when I extend my arms. Is this normal or should I be concerned? I don't lift anything heavy at all, and I've been drinking plenty of water.

I should also mention I am 34 weeks pregnant!

I'd mention it to your OB. My muscles area really weak and I get sore and worn out easily at the moment. I'm anemic and that's what's causing it. They'll just do a blood test and let you know if you're iron deficient, which is super common in pregnant women.
