preterm labor

Hi mga mamshies! Yesterday was my check up with my ob and nakita nya sa ultrasound result ko na im having contractions. A week before ng check up ko ng travel pa ako with my family. So ngayon ng nirerequire ako ng ob ko na mg complete bed rest. Meron po ba dito na same nangyari sa akon? Advice naman po jan. This is my first pregnancy. Thanks a lot!
