Hi - I am ttc and on a board there but wondered if any of you could help. I am 4-6 dpo and getting lower back pain - possibly not a pregnancy thing but it is weird, not like anything I have had before but funny shooting weird sensations in back - weird and odd rather than painful. Am feeling it a bit in my leg too when it happens. Does this sound like anything you've had? Sorry for inarticulacy of my description.
You never know - you night have both - sciatica and a pregnancy!!
I wouldn't think about the pregnancy bit too much 9hard I know) and just sort out whatever's going on with your back - see a gp rather than google searching...you could end up thinking you had all sorts of things!! I've convinced myself of all sorts of illnesses in the past!!
