Hi all I'm new to this and don't really understand but I'm trying to find out if what I'm feeling is normal , my babies breech and I'm 39 weeks I have a horrendous aching pain in my bum that's making me push as it's so much pressure , every time I try to go to the toilet there's nothing there to come out ... has anybody experienced this before ? Also have lower back pain and the occasional tightening across my stomach
