Eh, first thing, kalau you're worried, best to see your doctor or go to clinic quickly okay, especially if ada bleeding or anything doesn't feel right. Flek masa pregnancy can happen for different reasons, and only a proper check-up will tell you what's going on. A few of us mums went through this and honestly, the peace of mind from seeing the doctor straightaway was worth it! At 17 days, don't wait-wait lah, better safe than sorry. Take care of yourself!
