My period is a week late , have had both negative and faint positive tests. Had cramping all week but no bleeding. Also have other symptoms such as having to wee a lot , tired , mild nausea , constipation. If I am pregnant I would be just over 5 weeks so thinking should be a clear bfp now ? Or maybe am having a chemical pregnancy ? Does anyone have any advice or experience where taken a while to show properly positive? Thank you x
