Thanks @Dr Padmaja.. i took 1 crocin n got relief... it was at left side only. Thank you so much for the information. I will keep this in mind..

as recbecca said it sounds like muscle cramp , i hope you are better by now . if it is related to pre term labor , the cramp willbe allover your tummy, had urgency in urination , some increase in discharge , if th is no loose motions , fever , then you can use hot fomentation , apply local analgesic gel , gentle massage , take rest , and can use paracetemol 500 three times a day . if there is any loose motions , urgency in urination , bledding , decrease in fetal movements , fever , consult your doctor , have an ultrasound , blood tests , urine examination . wish you speedy recovery

Take care, drink barley water. It keeps your body cool.

Thanks.. its fine now

Lets wait for the doctor's advice.
