Look, it usually starts in the third trimester when the baby's weight increases. But if you see sudden swelling early on, please get your BP checked by your doctor immediately.
For me, it started in my 7th month, especially during the hot summer days. I just used to soak my feet in warm salt water every evening and it felt so relaxing.
Having PCOS made me prone to water retention, and my swelling started around 20 weeks. Don't worry, but do mention it to your gynac just to be on the safe side.
Normally, mild puffiness starts around 24 to 28 weeks. Just keep your feet elevated when sitting, avoid standing too long, and mention it at your next checkup.
