Leg swelling in early pregnancy can happen, though it's more common later on when the baby gets bigger and puts pressure on your veins. It could also be from hormonal changes or increased blood volume, but it's definitely worth mentioning to your doctor or PD just to rule out anything else like blood clots or infection, especially if it comes with pain, redness, or warmth in the leg. In the meantime, try putting your feet up when you can and staying hydrated, but do get it checked out to be safe.
Hello! How many weeks are you? I think symptoms might differ from person to person but I think it is normal to swell a little or feel a little bloated throughout pregnancy. If you worry, trust your instinct, and inform the doctor asap! It could be an early sign of pre-eclampsia. I was unnaturally swollen in my second trimester in my first pregnancy- it affected my fingers so much that I couldn’t really bend them!
