Tahniah almost due, sayang! Lendir warna koko tu memang nampak macam bloody show, tanda serviks mula melembut dan membuka sikit, which is a really good sign that your body is preparing itself. Someone in my mum group mentioned that even without contraction lagi pun, ramai yang dapat bloody show dulu baru sakit belakang datang kemudian, sometimes within hours, sometimes a day or two after. Memang first baby lagi, jadi do call your hospital or doctor now just to let them know, sebab they will guide you whether to come in terus or monitor dulu from home, better safe than sorry, dear. Wishing you a smooth and easy delivery!
