First mom who is curious when to make the pink book

Hi, pagi tadi check 1 strip jer. Lpas tu excited nmpak 2 line. Terus check lagi 2 strip. Alhamdulillah masih lagi 2 line. But overthinkers like me, pergi beli pregnancy test jenis cassette & dipntell utk dpatkan assurance. Alhamdulillah, semuanya 2 line. Kalau ikut tracker skrg baru 5minggu. Jadi, bila boleh pergi buka buku pink ya?
