Need as much baby dust and hope as I can get!!

Kennedy • Engaged to my soulmate! Gave birth to our little boy Kayden Kristopher 02.22.2016👶💙 Took 13 months of TTC with PCOS💕
So I took a walmart cheapie on the 9th and a faint line showed up. I was 4 days late at the time and I am now 6 days late and i tested with an FRER. I got a negative(not fmu and it was at the end of the day) Im never this late!! Im so worried. I was so sure I am pregnant. Ive heard some women can go up to half way through the pregnancy without a + test, has anyone experienced this? I surely hope I am I just wish I could physically see that BFP :(
