How long do your periods last ?

[Tinks100887]

Hi girls

Started what I think was af on Sunday 16th
More brown blood then a red flow,
Not hot heavier at all.
Used a tampon yesterday and hardly any things there.
So my period has lasted a day and half if that.

Does anyone else suffer from really short periods ? Last months was a lot heavier x

Could it be implantation?

I'm unsure.
I'm going to give it a few more days and then I'll take another test.
Did a test last Friday and bfn so I'm assuming it's just a weird af xx
