Swelling... high BP

Hi all, FTM... I have not had any swelling until today (30 weeks 2 days). My hands were swollen earlier but have gotten better now but now my feet are pretty swollen and are also bright red on the bottom. Also, I have high BP and my dr put me on low dose BP meds earlier this week. Is swelling/redness just normal in 3rd tri or is it due to my BP? Any advice or anyone with previous experience would be great! Thank you!
