Confused still

Johndora
I ovulated on the 9th and had sex the same day I've taken multiple pregnancy test and their all negative but my period is 2 weeks late. I am on medications that could cause false test results that I've read up on, what would u all think??? My discharge is white still with a slight pink tink, I cramp a little but that's about it. Answers from u ladies please, and no smart remarks were all human
