Should I be worried?

So I came off my period yesterday, and last night me and my boyf had sex, but when we'd finished we realised the condom split...and now I'm getting like bloody discharge...I know I should be worried anyway because like yeh he came in me but does bloody doscharge mean I'm preggs or is it too soon to know? I've realised that it could just be left over period but like idk....help??
