Salam! Aah, cramps sebelah kiri tu memang biasa during pregnancy, tapi better check dengan doctor just to be safe lah, especially kalau sakit tu terus-menerus or parah. I had a few friends yang experience jugak, some tu just ligament stretching, some ada isu lain, depends on your stage of pregnancy. Mana minggu you sekarang? Kalau worried, jangan tunda untuk call clinic, they'll put your mind at ease.
