TMI Alert!!!

So as of today I am 13 days late. Every pregnancy test is negative. I have only taken two test though, one when I was 5 days late and the other when I was 10. My doctor told me to just wait and call back if I still don't get it by Friday. I have had sore heavy breast, and sensitive nipples. My breast are also larger and the nipples are larger. I know this is not in my head because my husband has noticed these changes. I also have a constant creamy discharge in my panties. I know I am not pregnant because I have been pregnant before and the test always showed positive 3 days before AF was due. By now the HSG should be strong enough to show a positive test. This is beyond annoying.
