period

So basicially I'm due on my period in 3 days .. there was the tiniest amount of blood yesterday and a bit more today but not like how my usual period would be . I'm having no pain and it just doesn't feel normal . The last time I had sex was 3 days ago he wore a condom. But I started searching online and it's coming up with loads of stuff 
Can someone just relieve my stress and tell me IM just worrying over nothing
