Can someone help??

Okay so I got my implant out 13th March I had a period on the 21st that lasted 8 days. I ovulated between 6-9th April supposably so I was meant to start my period on the 21st (I think) today I wiped and there was light wipe of bloody. Very light coloured. But I took a test this morning and it was negative. Is there any chance of being pregnant and that being implantation bleeding, it’s went away not seen anymore ??
