Implantation bleeding or ovulation??

I feel like I post here a lot lol, but I don’t have family or friends and when I discuss it with my husband lol it’s understand but I know he doesn’t… so here I am again. I will be posting my the photo in the comments so please take caution!! … as y’all know hearts mean intercourse and green means ovulation which I just got out of ovulation a day or two ago…. When I got off my period recently I had the brown old blood come out 2 days later after I was off, thought it was normal…. Well 6 days pass and I was still having heavy brown discharge come out… I posted someone said if I took a test which made no sense since I just had my period… could any ladies give me some advice me and my husband have been trying to connivence for 3 years now, ended up getting pregnant last year and having a miscarriage…. I’m tired of wasting the pregnancy test, and getting my hopes up… 😩😩
