implantation?

Morgan • I`m 18 && blessed with the love of my life!💕 Hoping to have a beautiful little baby soon!🙌🏼
Last AF was Jan 14-20, have had all kinds of symptoms and have Bering riding the emotional roller coaster for a few days. You think this could be implantation bleeding or just and early period? It's supposed to be my 3rd day in my fertile window. What you ladies think?
