please don't ignore :/

Sunday night/Monday morning I woke up with period pains, back ache throwing up and just so uncomfortable unable to sleep again, later on Monday I rang the hospital and explained everything and they said it sounds like early labour and told me to relax and take pain relief. The pain wore off and just had a few niggles throughout the day. 
Tuesday night I had period pains again along with hip pain and achy legs and it was constant period pains but they would come stronger then dull down again so I timed them and resulted 5 minutes apart lasting around 40 seconds a time.  I rang the hospital again and got told the same thing, I had this pain on and off all night and disturbed sleep. Now Wednesday morning I've not having regular pains but it's on and off!? 
I've not lost my plug nor waters.
What does this sound like to you?
Have you experienced this?
