Hey congrats on your pregnancy!

Headaches and back pain can be common pregnancy symptoms. With my first baby, I reckon I had a headache the while second trimester! I guess it has to do with raised blood pressure and also hormones relaxing your muscles. Emphasis on 'I guess' since I have no medical training at all.

Have you found your Belly Buddies group yet? You might be able to compare symptoms and chat with others due around the same time as you.
