Waiting for a test results

So yesterday I called my doctor and was told to come in to get checked out. I was having cramping at irregular intervals some longer than others some going to my back. I got testing for uti and blatter infection and I also received a swab test to see what my chances are of going into labor on my own. If I was to receive a negative results there is a 97 precent chance I won't go into labor on my own and if I get a positive result 1/3 of women go into labor earlier than 37 weeks. I am hoping for a negative result right now I have had a baby at 35 weeks with my first child and then for my second I received shots that keep me from going into labor so I had to be induced with him. Its the first time in a long time I had to be worried about preterm labor. So far I have had a pretty good pregnancy with twins hoping I can make it to 36 weeks for now.
