Can I get pregnant while on my period?

My period started two days ago and last for seven days. I had unprotected sex yesterday and yes he did cum inside of me. It says sperm can last for 5 days in a woman’s body. My period won’t end until August 1st and according to <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> i won’t be fertile until August 10th... could I still get pregnant ?
