Should I take a test ?

aylin

So my period was due the 21st of Oct & I ovulated around Oct 4 and had unprotected sex . I still haven’t gotten my period but I did take a test Friday & drank lots of water then took a test and it came out negative . But I’ve been having symptoms of sore breast you can also see my veins they feel like he’s let when I take off my bra , & also fatigue . When should I take a test ? I just don’t want to see another negative :(
