Weekly "C" Check

My weekly cervix check was fine today. Same as last week 3.7. I tried to ask peri a few questions, but he didn't seem so inclined and I'm so tired I can barely see straight so I let it go since I am seeing my OB this week anyway. I did learn that once a cervix shortens, it's that way for the rest of the pregnancy. However, I also learned that if it doesn't continue to shorten by 24 - 26 weeks, it probably is not going to shorten. So, the biggest risk is in the next 4 - 6 weeks.
