Almost at our first goal. 27 weeks today

Today I hit 27 weeks with my boy/girl twins. Last week at my biweekly appointment we got sent for an unplanned sonogram. Our head OB didn't like how my son's heart rate sounded on the Doppler. Luckily everything was normal on the sonogram however he said that my uterus was measuring 31 weeks and both babies were down low, head down and in position. The pressure has been unreal and I am having tons of difficulty breathing. He said our first goal is to make 28 weeks. Once we get there our next will be 30 weeks but to be prepared to go anytime after that. I am scheduled for 38+2 but he said it is highly unlikely I will make it to then. I've been on "Princess Duty" for a few weeks now but I will be starting bedrest this week. 2 1/2 weeks ago our daughter was measuring 1lb 10oz and our son 1lb 15oz which is ahead of schedule. We go next week to have them measured again. It's so crazy that my due date is 11/26, scheduled delivery 11/14 but now I'm being told I could have September or October babies. Hoping to keep them in as long as possible.
