Pregnancy test kit

Hi i been late for 13 days period this month, last month my I'm not sure if I'm period or not as my blood does not flow or heavy much like normal, only 3 days but just a little bit like we having 5 days. Recently I'm having a miscarriage. And today i decided to check test kit again. Few weeks i did check with clear blue kit and cheap test kit but it was negative. Today the first test kit show faded. As I'm still not believe it. So i test again 3 hrs later, it show no faded line anymore.#pregnancy #worryingmom #pleasehelp #advicepls
