BFN but NO AF

For starters I have hypothyroidism and I haven’t been on my medication for a while now, me and my SO are not using any protection and we are hoping for a baby, my endocrinologist appointment isn’t until December 20th, My AF is just about a week late, I don’t have irregular periods. But I’m having so many symptoms that I am pregnant but some kind of go hand in hand with my thyroid, but one symptom is I’m constantly urinating, my breast are super sore and I normally don’t get sore breasts, my arms and breasts are starting to get really veiny looking I have more stretch marks around my waist and thighs and calves, fatigue, itchy legs, bloating, but all my tests are negative. I made a doctors appointment to try and take a blood test, let’s see how it goes.
