I'm having contractions every 20 minutes since about 3.30 - it's now 6.00, is this normal? They are getting stronger but not closer together. How is this likely to progress? Are there any rules? is this even real labour? I had some pinky blood down the toilet just after the 'contractions' started, in between the 'strong ones' that i feel it in my back and my stomach tightens up, it feels like constant period cramps. I'm due in 2 days.
