Bleeding

I am unsure of when I ovulated but my time of the month isn’t due for another 8 days, I am currently bleeding it started with a pink tint and now it’s a little heavier and is the second day of it however normally I am always 28 days never early, and normally I am heavy straight away with clots but this is really light, I’ve read some people can have heavier implantation bleeding so I’m hoping that’s the case with me! Fingers crossed
