Stressing myself so out. 😩😩

My story began like this. I don't test for ovulation every cycle I don't want to kill myself with that so I know the week of my fertile week to bd. So this month I get two cycle. One was a normal flow no complaints 17 days later her comes another. Wasn't spotting wasn't brown just light. Enough to fill up a panty liner. Rewind with my daughter and son I went through implantation bleeding not all what they say it look like for me but had two healthy babies. Fast forward now I go through what I think is implantation bleeding. Never have my cycle been early and not pregnant. But I always assumed it was so never really paid it no mind then next cycle when I didn't get af I tested and it was very faint line a month later. I feel I am I have so many symptoms but testing negative. I don't know anymore. I'm like whatever at this point. So who has has implantation bleeding. How long before you got your bfp
