I think the cramping "labour like pains" early on, I didn't have it but have the cramping my ob thinks it could be bub moving down and my SPD being irritated, I think it's just body preparing. I had a fast labour for #1 and expect my body is preparing for a fast labour for #2. If your worried talk to your caregiver... FYI I didn't have it in first pg so could be a second time round thing.
