Period lambat sehari dah test pregnancy, double Line pekat

Saya last period 26/5 nikah, 27/5 saya nikah. 27/6 patutnya start period but lambat sehari so try test pagi ni (28/6) terkejut ya Allah positif. buat test sebab 2 3 hari ni rasa kejang kat rahim kiri mcm senggugut tapi kurang sakit dia, breast pun mcm sensitif. so decide nk test eh positif. accurate ni eh
