Anything??

Is there any natural teas or any drink that it’s safe to take during pregnancy for energy? Anything to take as a pre work out that is safe during pregnancy? Between work, my two kids and doing chores and stuff it’s hard to find energy and time to work out. I’m 27 weeks and 6 days pregnant and I’ve feel like I’ve gained a little too much. This is my third baby, And before getting pregnant I was working out a lot and had lost a lot of weight, Now I feel like it was all for nothing.
