Is that a contraction?

Since I have been here I am constantly being asked if I am having contractions. I usually say "I don't think so." because I don't know what they feel like. During my morning NST I felt this slightly uncomfortable feeling in my lower back and abdomen, then across the top of abdomen. I thought to myself, I wonder if that's a contraction. When the nurse came back she said I had a contraction showing on the strip. One of the babies heart rate decelerated right after which can be concerning or normal. The doctor came and did a BPP (ultrasound) to double check them and they looked great. The contractions did not last long, but I felt tired and uncomfortable all day. Hopefully tomorrow will be better.

We just got done doing my evening NST the girls were quite wiggly this evening, but because the strips are 1 hour long they were still able to get what they needed and they said it looked good. No contractions on that strip.

Tomorrow will be 29 weeks, so I am excited about that. I want to thank everyone for all their thoughts, prayers, visits and phone calls.
