TMI.. whenever I’m in the heat for a long time

I come back inside and notice a lot of this type of cm lately. Now I recently moved to Texas, and it is really hot and humid. So I’m wondering if maybe it is causing this? It doesn’t smell... but I feel like maybe the color isn’t good? Does if look normal? Can heat cause increase in cm?

I’m also 7 dpo, and I am usually dry at this point in my cycle.
