Well I really thought something had started for me tonight but now that I've got out of bed again it all seems to have stopped

!
Had cramping in my back from around 8pm which has gotten worse and now painful but not regular. Had an upset stomach as well and have had to dash to the loo several times and I wonder if this was a clear out.
Got up at 11.15pm to time contractions then decided was probably false labour so went back to bed but woke up again at 1.15 with worse contractions but still irregular. The last three were 9 minutes apart, then 10 then 7 then 15, each lasting about 30-40 seconds. LO tends to move about in between each one.
Just been to loo and have started to lose loads of plug (first time I have lost plug) but contractions now seemed to have slowed right down (was about to type that they'd stopped but just had another one). Still feel pressure and aching in my back. I dont think they are painful enough to be the real thing and they arent regular but I do wonder if this might be the start of something.
Just made myself a hot milk and will pop back to bed again in a minute. Hoping I wake up tomorrow with waters broken!
