In desperate need of opinions and baby dust!

Morgan • I have a son born on Dec '15, another son who was born Sept ‘17, and an angel baby born into heaven Nov '14. 💓
So I deleted this app around the 18th of February because after 3 (currently on 4) months of TTC and nothing I felt very discouraged and stressed, so I figured why not just eliminate the pressure of BDing on "the right days" and just do it when the mood is right? So that's what we did. I quit keeping up with my BBT, symptoms, moods, ect. My fertile window was around the 1st - 5th of March (a LOT of ewcm around the 4-5th); we BD the 27&28th (of February), and 3rd, 5th, 6th, and 8th of March. Had brown spotting on CD 13-14 that I took for ovulation spotting so I figure I ovulated CD 15-16 (if not the day of actual spotting). So now I'm about 7dpo (period's due March 17-18th) and I've had a VERY substantial increase in creamy-watery CM today, on top of sensitive nipples and slight pinching sensations in mostly the right side of my uterus, sometimes toward the middle, and very very mild cramps (so mild that it feels more like pressure than actual cramps). And this morning I woke up with a slight metallic taste in my mouth. I know the fertilized egg normally doesn't implant until around 10-12 dpo but I've read that it CAN happen as early as 6 dpo. I've really been trying not to get my hopes up but it's so hard! I just need some words of wisdom from some of you TTCers and mommies.
