Big and Uncomfortable for a Reason

I've been feeling increasingly uncomfortable and tired lately. Simple tasks aren't so simple anymore. Giving the kids a bath, carrying a basket of laundry, even sitting upright in a chair feels uncomfortable. I thought I may have overdone it last weekend at the marathon- taking care of the boys most of the weekend, doing a lot of walking, etc. At my OB appointment yesterday I learned why I've been feeling so miserable. My uterus has grown a lot since my last visit. I'm 28 wks 4 days and my uterus is measuring 37 weeks. It's most likely additional amniotic fluid. I can't help but think this is the beginning of the end. That any day I could go into labor. This isn't a suprise, but the reality of everything is scary- the physical reality, the emotional reality. I don't know if I'm ready to face this yet.
