Spotting - pale red

I am 6 weeks and 2 days pregnant... Normal po ba na magkaroon ng spotting na pale red pero hindi naman persistent and buo-buo ang lumalabas? Is it still part of implantation bleeding or is there any other cause? I already sent a picture to my OB-Gyne but still no answer from her. My next check-up will be on June 9 pa kasi. May binigay na naman pampakapit last check-up ko nung Friday. Thank you.
