PERIOD BLEEDING OR IMPLANTATION BLEEDING???!!!

On Monday the 14th, I had sex and the condom broke. He never came inside me but just to make sure I took a Plan B the day after, within 24 hours because pre-cum can still get me pregnant. It’s been 5 days and my period is supposed to come on the 23rd. Is there any chance that I could be pregnant? (Also I wasn’t on my fertile week when we had sex).

I know that there are side effects to EMC like spotting but i’m still freaking out!!!

And when can I take a pregnancy test??
