Sakit tumit masa pregnant memang boleh jadi normal, especially kalau dah start showing and weight distribution tu berubah, a few of my mum friends complained about this around second trimester jugak. Tapi kalau sakit tu persistent atau getting worse, better check dengan doctor or physiotherapist to make sure it's just pregnancy-related and bukan plantar fasciitis or something else, sebab depa boleh suggest exercises or insoles yang membantu. Try wearing comfortable, supportive shoes and avoid standing terlalu lama mula-mula, then see how you go! Congrats on your first baby, all the best!
