I've heard people say that the day they hit the third trimester everything changed. Week 28 definitely felt different. I felt a little more tired, a little more uncomfortable, had a little more trouble sleeping, and felt a lot more like I wanted to do things other than be at my desk at work.
To add to the list, when I got to my office on Wednesday morning I literally could not walk. I managed to shuffle to my desk, only to continue to feel worse. I had a terrible pain on the lower left side of my belly. As the discomfort crept around to my back I started to worry about preterm labor. I called my doctor, grabbed my things, and got checked out. Once it was confirmed that the baby was fine and I was not having any sort of contractions, I felt a million times better. But, I still couldn't walk properly (or stand upright at all) and when the nurse touched my left side I nearly jumped out of the bed. Their best guess? Potentially a kidney stone. Oooof.
Supposedly kidney stones are fairly common in pregnancy due to all the extra stress your kidneys are under. Since they're working so hard (and you pee all the time), they simply aren't as able to process everything as well as usual. As a result, in addition to the other discomforts of pregnancy, kidney stones make the list of things that are more likely to occur.
By Friday, I felt back to normal. It was blissful. Not only could I stand up easily, walk, and had no pain, but my complaints from earlier in the week had also disappeared. I'm opting to call this a minor set back in a generally smooth sailing pregnancy.
On to week 29!
