This one better not wait, please go see your doctor or call your gynae today, especially with the water retention together with high BP like that. Post-partum BP issues need to be checked properly to make sure everything is okay, and your doc needs to know what's happening now while you're on medication. Take care of yourself, you just had a C-section two weeks ago.
Please get a confinement Nanny to massage you and always wear compression socks
