Aww sakit celah peha masa pregnant memang uncomfortable kan, terutama when baby dah besar sikit! Minyak panas boleh je, tapi I'd suggest ask your gynae first sebab area tu sensitive and masa pregnant kita kena extra careful, maybe ada reason better to avoid or ada product yang safer. A few of my mum friends kena same issue around 18-20 weeks and some guna warm compress instead of minyak panas, ada yang kena change position tidur. Tapi honestly, better check with your doctor jangan self-medicate, even with minyak saja, as a precaution. How long sudah sakit macam ni?
