well im nearly 31 weeks and just wanted some advice, last 2 days ive had period pains and lower backache, i have it for a few hour and then it will dissapear and then come back again my belly has kind of remained hard most of the day today too. this is my 2nd child and i cannot recall having period pains at this point with my 1st. so i was just wondering what it could be?? any advice appreciated
