pregnant test?

Bole sis. Tapi bergantung pd orang. Kawan sy lewat 3 mgu period baru dpt double line kt pregnancy test. Tapi utk saya, sy cek selepas 3 hari lmbt period. Keputusan upt samar2. Jadi saya tgu lagi 2 hari, cek lg dgn upt. Result positive. Last sekali try pula guna clearblue utk confirmkn. Dpt result 2-3 weeks pregnant. Tapi, kalau tak yakin juga, sis bole pergi cek klinik pula lepas tu.
