Advice please!

I am two days late for my period...before the last three months my period was irregular, but the last three months I started at the exact same date each time. This month I have had sex but protected each time, but once the condom broke in the middle of having sex but he pulled out right when it happened. I'm stressing out & I know that can have an influence on your period so I'm trying not to, but I don't really know what to do 😫
