Should I test?

Alyssa

So on March 9th I had sex with my boyfriend and it was unprotected but he pulled out. So March 26th I was supposed to have my period but it’s a day late. I have period symptoms but I keep checking and no blood is in my panties or coming out of me. So therefore I’m late by a day and just so happen I think March 9th was one of my fertile days. I know sometimes your period changes dates throughout the year and with the seasons but is this normal? I’ve used the pullout method many times before and I’ve never gotten pregnant. Could this be a time where I wasn’t so lucky and ended up conceiving? Should I take a test?
