Sayang, if there's bleeding yang tak normal atau on-and-off macam ni, you really need to see a doctor or go to the clinic ASAP okay, jangan delay! Could be many things, tapi kita kena check dengan proper medical checkup to make sure everything is okay. A few of us mums have had similar worries, and honestly the best thing is get a professional to look at it rather than guess-guess. Please make an appointment or go to your nearest clinic/hospital if it continues, better safe than sorry! Sending you strength sayang
