Trouble catching my breath and a bad headache today. And no matter how much liquids I drink (8 oz water, 2- 16 oz glasses, a 24 oz plastic water bottle, a 6 oz box 100% apple juice, a few sips totaling like two oz koolaid, and another 16 oz glass water) and I am still freaking thirsty and have cotton mouth. Add in that if I walk more than two or three blocks, I start having actual contractions. This pregnancy has not been kind to me.
