Is anyone else just struggling? 😩

Morgan
I'm trying so hard to remain active and eat the right foods, but it's like my body is just struggling. I was going to do a light workout this morning and just changing & bending over to put my shoes on sent my heart rate WAY up. Pulling my pants up made my arms hurt. My calfs are cramping. I just feel hot & weak. The past few days I've felt like this. 
My moms a nurse and she checked my blood pressure & blood sugar and both are perfect. Only thing is my pulse is high. 
Anyone else feel this way? I'm 32 weeks tomorrow and feel like I still have way too long to go to be feeling like this already.
