It was my mucous plug and it turns out i was having contractions every 2-5 minutes. turns out i've been having them for about a week or so and just thought it was babies pushing/stretching. At the worst today they were a minute apart. They tried iv fluids and procardia first and they actually increased. The doc came in and checked my cervix. Luckily it is still high, firm, and measuring 3.7 cm. They switched me to terbutaline and its calmed them down finally.
They are keeping my overnight to continue to monitor. Hopefully i'll go home tomorrow on terb pills with bedrest orders. Babies look great and the fFn came back negativeI'm scared but for now things are calming down and holding steady.
