Wa'alaikumassalam sis! Jangan stress, buku pink boleh buat anytime, memang banyak mums tunggu until later in pregnancy or even after delivery, especially kalau situation macam sekarang sibuk dengan quarantine. Once family is cleared, you can go to your nearest clinic or hospital to register, memang senang je process dia, usually in one visit saja. Take care of yourself dulu, and kita uruskan admin punya thing later okay!
