Implantation or just spotting

Rachael
After not been on birth control for 6 years and suffering with a ectopic pregancy and very strange periods and previously suffering with rupturing ovarian cycsts  very confused at what I just seen when I wiped. My period finished on 7th after been logged as a 4 day cycle (first two days were regular flow last two days just odd spotting but this has become a normal period for me). Today is 11th and when I wiped a small amount of clear mucus with a light pink tinge .. Can only describe it as looking like like sweet chilli sauce haha. Never in my life had anything like that in my life. According to glow my fertile window is in 2 days time. Im having regular sex even on my period and only not had it about 4 days in 3 months so confused by this discharge could it indeed be implantation? It definately isnt last dregs of period as since 7th been no bleed or spotting at all. Very confused.
