Just made 26 weeks today and I woke up to get ready for work, got to work and I'm just tired. Tired as in still sleepy and I don't understand how because I went to bed early last night got about 12 hours of sleep and I'm literally just tired of being pregnant now and I'm not even 30 weeks yet. Feeling like I can't even drag my heavy body around anymore and walking is a chore. Mind u I'm not that big and have so far only gained 10 pounds this entire pregnancy but I feel like I have bricks attached to my legs and I just can't do the walking thing today but I have no choice walking and standing is a huge part of my job and I have patients who depend on me! Sorry I'm on this huge rant but that's just how I'm feeling today. Anyone else around 26 weeks and just feeling like their ready to be done? I just want my regular body back.
