possible extremely vvvf

3 wks 1 day after miscarriage. levels went to 0 pretty much straight away also had back to negative tests. everything was fine. however past few days been very tired,nauseous just not myself. normally I wouldn't be due af for another 10 days (however 1st period since mc) just poas even tho I thought would be blank negative as assuming by normal af it's very early to test. I had to

turn my brightness up to see better as it's that faint however it seems like there maybe something extremely vvvf showing (like really faint. remember from normal af still have another 10 days) is it possible for this to happen,not an indent or evap has slight colour in person. Well within time frame. just wondering obviously I will be retesting
