blame it on the period?

Terrible day 😔 i woke up just to find out i had gotten my period. Everything was stained. I get to college and my bf texts me to say he'll be late (we take the first class together), class is over and he still wasn't there so I got worried and called. His car wasn't working. Got to second period to find out that the test that I had studied, which also was with open book I got a 66 and was 25% of the grade I felt bumped and immediately my eyes watered. I call my bf once again, I was desperate to see him and hug him. He said he had to go back to his house and couldn't make it to college. I bursted. I only wanted to see him. I wanted to leave, my parents were working. Had to stay here. So I'm in math class typing this and my tears won't stop falling and now my glasses are like a pond. Should I blame it on my period? I didn't see my bf yesterday and apparently I won't see him today. UPDATE: saw him, he shaved his mustache... couldn't get my hands off him. 🙄
