Advice please!

Hey ladies, I’m so heartbroken and confused. Let me start my saying Normally, with my period, I have light blood All day then day two and 3 are heavy. My periods are regular. I recently took two pregnancy tests in which I’ve received faint positives on both. I’m almost 100 percent positive I experienced implantation bleeding last Thursday. I am currently 3 days late for my period. Well, Yesterday I wiped and it was just a little light pink/ brown blood. I became really emotional as we have been trying for 13 months to conceive and I thought something happened. I don’t have spotting before periods. However, I’m not bleeding anymore and didn’t bleed any other time yesterday. I’ve been confused and a mess since yesterday. Has anyone ever been 3 days late for period and had a little brown/ light pink blood then was actually still pregnant? I’m assuming I’m somewhere between 12-14 dpo. Took another test this morning and still faint line, however I know some ladies don’t get the BFP until later dpo. Any advice really helps
