I am almost 34 weeks and I have days that I don't want to get out of bed along with days that I find energy to do stuff....I'm sure it's different for everyone but it's definitely normal to be real tired in trimesters 1 and 3.
I'm 32 weeks also... and I sleep constantly. I also have a really bad headache when i wake up from every nap until I drink some ice water or have something with a little sugar in it. like koolaid... it's my fave lately. lol.
