Hi so I'm sure I'm clutching but befor my late period 4 days my period appeared started bright red blood on Friday pm and flowed into Saturday useally I have to keep changing pads sorry tmi but there's more when I wipe than on the pad today it seems lighter still there but feeling like it will be gone by the morning, boobs are still sore would you test again or just get on with new cycle? Anyone been there?
