I took 1 test(normal hpt test with lines) 2 days after my period is due, and then another(digital) 5 days after my period is due, and both tests came out to be negative. and its been 7 days and i still don't have my period. My boyfriend and I had protected sex and it only lasts less than 6 minutes. and was for sure the condom did not break nor leak. 

and btw ive been having white thick and dry discharge. 

and this is really freaking me out as to why i don't have my period yet. 

additional information: I have been working out a lot lately.
