Please give me what you think

TTC #2 since June 2017 ( I stopped taking my BC) . Normal period 1/5/18-1/13/18 which was a day or 2 longer than normal for me. No big deal. We BD the 14th-16th & also the 19th,20th, 22nd & 26th. Well for some reason I started spotting off & on ONLY when I would wipe and not every time from 1/25/18-2/3/18 then it was gone completely. It was a very light pink, sometimes maybe an orangish tent , sometimes brown. This was a week before I was due(next cycle should’ve started on 2/3/18) and that NEVER happens for me. I tested on dollar tree test 2/3/18 and BFN. I also never spot in the beginning just the last couple days. I am never early. Then fast toward a little bit because AF never shows after that until 2/20/18 after BD I started for like 3 hours & it wasn’t heavy like normal. Then 2/21/18 I start the weird spotting again only when I wipe & that night it was gone and nothing has happened since then. Any opinions? I don’t track temp or ovulation, glow says I ovulated 1/19/18 but we all know you can’t go by just that.
