Period or pregnant???

My boyfriend and I had sex a few days ago without protection, which is rare, but I’m supposed to start my period at the end of the month and it still hasn’t come. He did pull out and came on my chest, however.

I’m getting the normal clear discharge before your period does start, and a lot of period symptoms. My anxiety may be getting to me, but I am concerned.

What do I need to do?

UPDATE:

I took a urine test, and it came back negative. Just looks like my period is just annoyingly late. Thanks for all the help!
