It can happen.
Your body is adjusting and your hips are widening so your lower back and that whole area could get achey.
When I was in the early stages I got bad hip pains, like they felt like "growing pains" and it ached so bad.

Just wait till you get to the third trimeseter.. your back will litterally KILL you!!
My back still does and Im 4mths post partum.

I got my back pain early in the pregnancy as well, maybe around 8 weeks though i had a previous back problem prior the pregnancy. Everyone is normal. Congratulations

I had a little bit of back pain around 7 weeks and then it went away..then it came back really bad at 14 weeks. Now sometimes it hurts for a few days and then stops.
