Late period need advise fast !

Okay so I was supposed to get my period on May 5 and when it didn't come me and my boyfriend had sex again now my period hasent come and is a day late. We used a condom and he pulled out befor he came each and every time we were active should I be worried ? I've had a lot of funkywhiteish yellow discharge but no period yet should I take a test I'm seriously freaking out I'd also had small cramping
