Haha betul tu! Honestly, a few of us preggy mums juga confuse sebab minggu dengan bulan lain macam, tapi once you understand the pattern sikit jer, most apps memang ada built-in calculator yang buat hidup senang. Your chart tu memang helpful sgt for first-time mums yang tak sure berapa exactly diorang dah pregnant, senang jer tengok visual & tau what to expect every trimester!
