Exhaustion

It's tiring being pregnant. Quite the tiring experience. And this morning my legs hurt. And my feet. I feel like I had walked 15 miles (and no, I haven't). It's a weird internal pain that I can't really identify. I really don't want to check the 15 pregnancy books that I have upstairs because I don't want to start getting weird ideas or something. I am tired of those books as well. I haven't read them in a while. Whatever it has to be, it will be. I'm completing 27 weeks on Monday and that puts me close to the end of the sixth month ?? Maybe. All these weeks and months in pregnancy is very confusing. Because it is not 9 months, no, no, no it is really 10 lunar months of 4 weeks each. It is really a long time. I wonder if human beings are the mammals with the longest gestation? I feel I have been pregnant forever and I still have three more months...
