Pregnant?!

Hi everyone, I could use some advice. It might sound silly, but I'm worried. I usually worry quite easily, but still... I had sex with my boyfriend on Saturday, but I forgot to take my Saturday pill. I took it Sunday evening along with my Sunday pill. There was more than 12 hours between them. I don't know if it's related, but when I took both pills on Sunday, my pill strip was empty. Normally I should have gotten my period today, but instead I have a thick white discharge, exactly like during my fertile days. Should I take a test, or am I just worrying too quickly? Hearing it from someone else would probably put me more at ease. Greetings
