Bloated after ovulation?

Im 4 DPO, I've been TTC for 6 months now, and as far as I Can recall ive never felt this bloated after ovulating.

I feel like ive gained 10 pounds, which is impossible because ive cut back on calories a lot and have been moving around more.

Could this be an early sign of pregnancy? Along with faint twinges around my uterus and a migraine today?
