Aww sayang, memang scary kan kalau ada flek darah time pregnant, tapi alhamdulillah baby okay dulu, tu dah good sign! A few of my mum friends ada yang mengalami ni around second trimester, and memang sometimes boleh from cervical irritation, intercourse, atau even just hormonal changes during pregnancy, tapi since doctor dah check and everything looks good dengan baby, that's the main thing. Stress dan kurang rest boleh lah trigger spotting sometimes, so mungkin try to rest more, minum banyak water, dan avoid heavy lifting ja. Kalau flek tu terus-terusan atau jadi heavy bleeding, do pop back to hospital k, tapi since dah check dah, I'd say monitor ja and try to relax sikit, your body memang complicated during pregnancy!
