Spotting & Cramping AFTER period

Hey guys so the day of my last period was May 24th lasted for 6 days but very lighter than usual. Yesterday, I started cramping and having pains in my stomach and back. I went to use the restroom around 9 pm and there was a streak of what looked like like pink-brown discharge or spotting. Today, the cramping continues and the spotting as well but it’s a really light pink color. I need help. Is this implantation or ovulation bleeding?
