Cycle Day 37 No AF BFN

I am on cycle day 37 and my period still hasn’t started I have been testing since after cycle day 27 every few days and I have been getting BFN after BFN I assumed I wasn’t pregnant because of all the negative test results so I started drinking coffee and wine again as usual.

I am starting to worry that I may have ovulated late because I did travel to Europe and went through a 9 hour time change and my cycle was off last month (7 days late).

I would be so ecstatic if I was pregnant but I really want to know ASAP so that I can give up the caffeine and wine if AF is just going to show up anyway. I heard drink till it’s pink is okay anyway but I wouldn’t want to do anything harmful. Is it possible that I’m testing to early?

I used both $ store tests and 2 First Response Early Response and all were negative. I made an appointment with my OBGYN but it’s not for two weeks!

Sorry for the long post!
