So yesterday afternoon I started having cramps and back pain. I couldn't sleep well last night because I kept waking up in pain. They felt like contractions but I just tried to ignore them. Today I am having constant cramps, my back hurts and my belly has felt tight almost constantly. Iv also been feeling dizzy and nauseous. I just don't feel right atm. Could theses be pre labour signs? I feel abit different. I'm 37+5 x
