Weight gain question

Renee
From finding out I was pregnant to my 37 week appointment I gained 10.56 lbs. from my 37 week appointment to my 38 week appointment, I gained 5 lbs! Is it a big deal to gain 5 lbs in a week? I just thought that was interesting because I've been slow and steady the whole time. My eating hasn't changed, my swelling is no more or less than it was last week, and my belly measured 38 cm which is exactly where it should be. Just thought I'd ask you ladies!
