This morning i woke up and had diahorria, then about 30 mins later at 9.15am i got like sharp pinching pains in bottom of my bump and bump going tight, this has been going on now since then and they are coming every 10-15 mins but are getting slightly stronger. I have also got back ache now and feel wierd like i have no energy in my legs. I have never been in labour before because i had a section with dd. I have been walking about and cleaning but when walking about they seem stronger. Any advise would be great, thanks.
