Worried about missed period

Delaney

Hey guys, this is my first time posting. But I am currently stressing out super hard.

So last month, my boyfriend and I did plan B twice. And I ended up having my period twice in one month.

Now, we have been having sex this month with gel spermicide. However, I am about 3 days late on my period. I'm probably going to pick up a pregnancy test Monday if aunt flow doesn't show up by then. But what do you guys think? Is this normal? I am honestly worried.
