29 weeks and suddenly in pain

I don’t know WHAT happened but as soon as I hit 29 weeks everything went downhill. My whole body hurts. Yesterday I went to the mall to run errands and within an hour of walking around my back was on fire and my legs felt like jelly. I don’t recognize this body and I don’t like not being able to do simple tasks like running errands. Last night I was making dinner for my toddler and I dropped a glass full of water and it shattered all over the kitchen. I actually started crying thinking about how I had to clean the whole thing up. I’ve been pregnant before so I knew the discomfort was coming but this time it seems worse? Maybe it’s because I have a toddler to take care of whereas my last pregnancy it was just me. I dunno. Any words of encouragement would be great. I just feel so down right now 😔 I don’t know if I can make it 10 more weeks if it’s already this bad so early on.
