Ovulation day was the 5/01/19 at 14dpo had very light spotting only when I wiped.... I did poas before hand and all negative 🙁then I bled (period like type) but light and had stringy bits on tissue when I wiped. Anyway that lasted 2full days. Soooo with me been a dickhead and and cannot resist buying tests and doing them in the picture the top test is from Monday 28/01 fmu and is negative then the bottom test is from the 29/01 smu and that’s how it tuned out it has colour. And all were read and taken within the time frame........ I guess I take it as invalid/negative

What do you guys think?? Please
