is this implantation?

Kelsea

Okay. Period ended the 8th, had unprotected the 9th, 12th, 14th, and 15th. Ovulation starts the 15th to the 21st and I've had A LOT of discharge but today I'm like lightly bleeding. It just started at about 4 and its been 9 days since my last day of last period. Advice?
