i'd really appreciate some input 😊

Sydney
my SO and i had sex (unprotected) on may 28th (i ovulated on june 2nd according to this app) about a week or so ago i noticed a strange smell (like rotten eggs) coming from my pee and figured it was just a UTI bu a couple days ago, i noticed that my breasts are kind of sore and i am seeing more viens become more visible
is there any explaination to this? 
my period is supposed to come around the weekend and i'm nervous that it might not (my period can last from 5-7 days)
