Oh dear, baca ini pun rasa sebak, you are so strong for carrying all this alone at 39 weeks with a sick child and husband far away, please know that what you are feeling is completely valid and it is not manja at all. Since you mentioned ada lendir darah and you cannot tell if the pressure you feel is contraction, I think it is best you call or go to your nearest hospital or klinik now just to have them check, because the nurses and doctors there can really help you understand what your body is going through, and you should not have to figure this out alone. You and your baby's safety is the most important thing right now, sayang, please reach out for help, even from a neighbour or family member to be with you today, okay?
