Just want to know if anyone might know something

Ciara

I’ve took a plan b on April 14th a month ago I haven’t had a period a month long my cycle days are usually 27 day’s length but I haven’t gotten one the only blood I’ve been receiving is spotting I would might bleed one day and the next day when I wipe it’s clear no blood at all I’ve feeling pregnancy symptoms but every time I take a test the tests comes back negative so I was wondering if this had happen to anyone else
