It's Hit Me

My almost 26 weeks of pregnancy have finally hit me. Up until lately, I've honestly been feeling really well. Lots of energy, upbeat, still exercising, etc... Last week I started teaching summer school, and I don't know if that's what's doing it to me or what, but every day I am wiped out! I can't wait to take a nap or get to bed early. I don't feel like doing much around the house with cleaning or cooking (okay, I've never really cooked much...)and the exercise has completely taken a back seat. I'm just not feeling like myself lately.
