Confused!?!?

Cassidy
My boyfriend and I had sex while I was finishing up on my period and I let him finish inside. That was over 3 weeks ago. I have both Glow and <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> and on Glow my period is over a week late but on <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a> my period is supposed to start today. My breast hurt, I keep getting heart burn and I have no other period symptoms. I had an abortion last May and had the same symptoms. Should I take a pregnancy test or wait another week? Any advice would be appreciated!!!
