Eh, totally normal lah! 34 weeks is quite advanced, your body is working extra hard to support baby, plus the weight pulling down on you makes everything feel heavier, so no wonder you're exhausted. A few of my mum friends were the same, one even said she could sleep standing up at that stage The good news is this is usually a sign your body knows what it needs, so try to rest when you can, those naps are actually helping you prepare for labour and the newborn phase ahead. That said, if the tiredness feels extreme or you're getting shortness of breath or dizziness, better check with your doctor just to be safe, because sometimes it can be related to iron levels or other things that need a quick look-see.
