Ay congrats sa baby mo! Leg pain during pregnancy is pretty common kaya hindi ka lang, a few of us had the same kirot especially around mid-pregnancy, kadalasan it's from the weight gain, hormones, or sometimes the baby's position na nag-press sa nerves. Best to mention this to your OB in your next checkup para ma-check properly, lalo na kung tumatagal or umuusbong ang sakit, kasi they can rule out anything else and give you safe ways to manage it like stretching, rest, or prenatal massage.
