I'm so pleased to see this thread and that your baby was born all safe and sound!
I am 14.5 weeks and experiencing low aches/trapped wind and a sore lower back! I've been sending myself crazy on google advice all day and have come to the conclusion to mention it when I see my OB on Friday, but not worry too much till then!

I've always had a bad back and trapped wind (sorry TMI) before the pregnancy and I'm asuming the aches and pains are stretching (had urine tested last week). I thought the 2nd trimester was meant to be the easy bit!!!

Excited for the moment I'm sleep deprived caring for my Bambini.
