Google didn’t help ..

I’m currently 33 weeks pregnant. Since I’ve been awake this morning my body is very fatigued. Walking seems like a burden, holding my 1 year old was incredibly tough, and I’m out of breath in no time with movement. My heart rate is averaging around 90 while I lay here, so that isn’t terrible.

When googling I just get ‘33 weeks pregnant your body will start to become tired..’. No, my body has been tired but today it’s on another level than before. I was wondering if I just need more water or what others know about it..

Thanks!
