unsure of implantation

i had what i thought was implantation bleeding because i had very light brown spotting and light pink for about 3 days so i knew it was probably to long for it to be implantation so i started thinking i would start my period but i haven't had a single spot of anything and it ended about 2 days ago. my ovia app says to take a pregnancy test since my period was supposed to start today but <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a> says 5 more days. i've been cramping and i'm so impatient to test😩
