Burst of energy?

Amber
Has anyone else had a burst of energy out of no where? I've been completely miserable and all the sudden I feel the need to do everything. I've deep cleaned my house and today I pressure washed my carport and patio. Sprayed round up and picked weeds from the flower bed. 3 weeks ago I would have said oh hell no. Anyone else going through this? 34 weeks and 4 days with twin girls.
