Anyone else sooo exhausted?

I’m 6w3d according to my last cycle but man I feel like I did when I was 40 weeks with my son. Shortness of breath from just walking, arms feel super heavy, pressure in my uterus, waddling, nausea but no real appetite, irritable… the list goes on.

Now I’m psyching myself out on what if I am pregnant with twins? Or worse, a molar pregnancy??

Ugh. Trying not to stress but my first appointment isn’t until I’m 9w2d. Anyone else going through crazy symptoms early on?
