5DPO Feeling Super Nauseous and Aggy

Adriane
Decided to take a test today, thinking that a positive would show even though today only marks 3 weeks pass the first day of my last period. I'm guessing I should take another test in a week? Glow says my period is due in 10 days. My cycles have been irregular every since I took the mirena out June 2016. Last month was my first normal 28 day menstral cycle. Anyways. Rant over :)
