Period is 5 days late, no PMS symptoms at all

Hello, husband and I have been trying to conceive for a few years now, just hasn't happened for us. I've done all the tracking, I've used preseed and all that fun stuff. Been to doctor's and they say I don't have PCOS though I once upon a time had hormone issues, my body was creating a lot of testosterone and not much estrogen but my hormones are leveled out now. My cycle is about 29 days on average, I've had spotting with previous cycles and PMS symptoms but not this time. I usually start my cycle 2 days earlier than glow app predicts but not now. I am currently on day 35 of my cycle and still no period. My chin usually breaks out before my period, along with spotting and breast tenderness for an entire week prior but none of that this time. My back has been hurting a bit and I feel a little gross when I go to lay down at night with a slight frequency in urine but that's it. My period was due on the 20th, took a test on the 25th and came back negative. I'm really hopeful that I just don't have enough HCG built up for it to show yet, I really want that BFP and will be retesting again soon. Anyone else experienced similar and gotten a positive or am I just wishing on stars?
