chemical pregnancy? help

Brittany • I`m 23•• currently pregnant with my first little angel blessing 💙👶🏽
2 nights ago I had what I believe was my implantation; strong pinch in lower right side followed by light pink tinted discharge. the next day(yesterday) I took a test after work even though it was quite early and got a veryyyy faint but there second line. today woke up this morning with brown watery discharge more so than I was having the pink. is this me having a chemical or could it just be from the implanting still. please help, so upset. would love your opinions. 6 days until expected period now.
