as much as I'm happy to be pregnant does anyone else get frustrated by the physical limitations that it brings sometimes? I'm almost 25 weeks and just running errands and light cleaning exhausts me. I work full time as a teacher but Gosh dang I'm exhausted and so moody. I'm carrying my son super high and I'm HURTING sometimes! I feel so wimpy but this is not for wimps.
