Please Help !! Any Moms On Here

Okay So This App Has been VERY ACCURATE FOR MY CYCLE Timing & For Almost About A Week I've Been Spotting. For The First 2 Days I Just Thought Maybe My Period Could be Starting Early , But It's Still JUST Spotting Almost A Week Later . . The App Said I Shouldn't Be Starting My Next Cycle For 3 More Days . . Could I Be Experiencing " Implantation Bleeding " - The Blood Color Has Been A Bright-Light Red & Sometimes Brownish . . Me & My Partner Don't Use Protection Since I'm Allergic To Latex , I'm 21 & Haven't Been Through This Before , I Want To Ask My Mom But TO BE HONEST She'd Would Probably Freak Out . . I Need Some Help PLEASE
