A week late

I’m officially a week late. I took a pregnancy test today using fmu and it was negative. There’s been no sign of AF. What do I do? Do I wait to see if she shows up or go the doctors? Would they be able to see if I was pregnant and had a false negative? If I go to the doctors how long should I wait to go?

My cycles are always 26-29 days long, sometimes 30. I’ve tracked for 3 years now. I didn’t track ovulation this month so I’m not sure when I did or if I did. I’m on cycle day 36.

I’ve been trying not to spot symptoms and if I do I tell myself it’s my AF because all the symptoms are the same 😭
