Lower back pain is common in early pregnancy because everything is stretching out and can cause pain in your back. If it is really severe though, I would call the doc just to be sure its not a sign of a problem. Sounds like you're fine though! Congrats on the pregnancy!
lower back pain is one of the most common complaints from pregnant ladies in the first trimester. i am expecting my 4th baby and this is the worst back pain i have had out of all my pregnancies, hey ho, fingers crossed once we hit 13 weeks we will feel much better!
I've been having lower back pain ever since I found out we were expecting. It feels like right in the "but bone" is where there is pressure. DH rubs it and it goes away. I've also have been flip flopping for weeks now, but can finally lay on my side without so much pain.
