I'm on the pill and  I'm meant to start my period today but two days before I had light pink spotting and then today I wiped and it's more reddy blood than pink but very light not much is on the pad hardly any but when I acc go to fully check my vagina there's a lot and it's a vibrant red so I don't whether this is my period or if it's implantation bleeding mistaken for a period? Any comments would really be appreciated
