11 days late

So I’m now 11 days late. I average around 32 day cycles and I’m on day 43... I was supposed to get AF June 14th but had two days of brown CM only when I wiped.

Since then I’ve had very light cramping, lower backaches, feeling very thirsty, headaches every day, but my boobs aren’t sore like I typically get before AF. I’m also incredibly fatigued, even before I get out of bed in the mornings. I tested on cycle day 37 and 39 with BFN.

The cramping doesn’t feel like it does with PMS though and I feel a constant pressure with the off and on cramps. Any insight on if this could be early pregnancy? My hubby and I have been ttc for a year now and had just decided to take a break from trying.
