I have spotting issue too on week 5.. This is threatened miscarriage.. Dr should have started you on progesterone med.. The duration of spotting (light bleeding) varies.. Some ppl resolve in a few days, some a few weeks. What you should do now is to stay relax and rest more. At the mean time, monitor for your spotting / bleeding.. If it gets more (blood soaked the sanitary pad, similar amount as period), then will advice you to visit gynae immediately as miscarriage might happen.. Any bigger blood clot (size bigger than 50cent coin) also something we need to worry.. Stay relax and optimistic for now until Yr next gynae appointment, some ppl have weeks of spotting but manage to have smooth pregnancy with healthy baby also.. Take care ya, mummy 😊
