question??

My story goes as this. went into pre term labor at 32 and a half weeks.... contractions made me dilate to 4cm and 80 percent .. baby at station -2 .... got put on mag sulfate to stop the contractions and the steriod injections to devolope her lungs, and was sent home with procardia to take twice daily to also help contractions. ...... I am now 34 weeks and my contractions are starting up again something horrible. nothing able to time.. but when I have them they are bad and paunful. medication is no longer helping .. doc says anything after 35 they won't stop my labor bc baby is good is a good weight and has had the steriod injections... but I want to try to keep her in there till at least 37, so my question is... any mammas have any recommendations or tips on what helps them threw their really painful contractions? I've tried heating pads.. showering .. Tylenol . .. laying on the left side, drinking water .And I'm on modified bed rest so I'm not really active either. .. I know they will be painful really no matter what... but man I'm getting annoyed lol.
