Stressed&Sad😭

I went to my do its office this Wednesday at exactly 32 weeks for a normal visit. Was having an extremely good twin pregnancy so far. My doctor did a pelvic exam to my surprise and his I was very short and soft and opened 1-2 cm. he sent me to be in bed rest at my case room. Once I got there they put me on monitors and once again to my surprise I was having regular contractions 3-4 min apart. This is my first pregnancy and I had no idea those where contractions that I was feeling. They've been giving me medication regularly to stop the contractions which seem to be working and 2 injections to speed up the maturity of their lungs. We are are trying to keep them in my tummy until at least 34 weeks but I am petrified and taking it one day at a time hoping for nothing more to progress. Please keep me and my girls in your prayers. Over here in bed I feel it's all I can do, other then try to relax and stay strong for my girls
