Hai mama, aku faham lah, first trimester memang rough, hormones naik turun dan badan pun mulai adjust. Sakit tumit dengan pinggang tu actually common, especially bila you've been resting a lot, sebab ligaments jadi lebih relaxed dari progesterone tu. Best thing is jangan stand up tiba-tiba lepas lama duduk, stretch sikit dulu before you get up, pastu try wear shoes yang support better (jangan flat sangat lah). Kalau sakit tu persistent atau makin teruk, better check dengan doktor ye, just to rule out anything else dan dia boleh refer you ke physiotherapist yang boleh bagikan exercises yang safe for pregnancy, many mums rasa relief after few sessions. Take care of yourself, mama!
