Sayang, symptoms macam ni memang perlu check dengan doctor sebab tak boleh guess-guess. Lepas haid keluar darah lagi, sakit payudara, sakit pinggang, dan tidur tak tenang, ini kena see a gynae as soon as possible, okay? A few of us mums pun pernah ada bleeding di tengah-tengah cycle, tapi banyak reasons boleh jadi, hormones, cervix issues, or something else, so jangan worry sendiri, just go get checked out properly. Could be nothing serious, but better safe than sorry, kan? Go make an appointment today or esok pagi if boleh. Take care!
