please help me

I’m getting a full weeks worth of my period every time i have sex. i’ve got the implant in, and it’s been happening since then.

My period only usually lasts 3-4 days but now it’s at least 5, and occurs almost immediately after sex.

Has this happened to anyone else? Did it go away on its own?

It happens really irregularly, some months it’ll happen straight away every time i have sex, then i’ll have a month where only my normal period comes and i won’t get it after sex.

Please help i’m so sick of getting blood on absolutely everything
