Unsure

Hey guys I’m new here so I’ll give this a crack. So I get regular period cycles (28-30days) each month from the first time I ever got it and never had a problem with it. In July 2017 I took out my copper IUD and the first day of my last period was 21st of September 2017 and I haven’t gotten it since. I have tried different types and brands of pregnancy test and they all came out NEGATIVE. I’ve been feeling extremely tried than usual, sore boobs and vaginal discharge (clear & thick) Then I was doing a lil reasearch and tried the sugar homemade pregnancy test. Sugar didn’t dissolve it just sat on the bottom clumped. Has anyone tried this and what was the outcome ?

ps. I have a docs appointment on Monday but in the meantime im curious.
