I don't know what step to take next, and it's making me so upset!

So I'm 2 weeks late. All tests are coming up negative. But I am a very regular 28 day cycle person and never been on B.C. So for around 13 years I've had an on time monthly period with no off months. Going by the start of my last period, aug 29, id be 6 weeks pregnant now. Not sure how that works since I only ovulated 4 weeks ago, but that's how it calculated it... either way, I just feel it in my bones that I'm pregnant. Dr won't give me a blood test saying that only 2 weeks late isn't enough. But I know my body. I eat spicy food all the time with no problem, and have had heartburn daily. And even woken up with it. I had mild lower than normal cramping days 5-7 after ovulation-implantation? Then yesterday I just started mild cramping similar to period cramping, but not even close to what my usual cramping is, which I read that in the 5th ish week is your uterus expanding? I know people say it's normal to skip a month due to stress, but this month I actually didn't even try to conceive necessarily! It's my 9th month so I just let things happen as they may without tracking, and I've had much more stressful months than this one past so I doubt it's from stress. Of course I'm getting stressed now because I need to know if I'm pregnant or not and get my baby the care it needs! I'm taking my prenatal, have been. I drink water, no alcohol, no sushi, no soft cheese or deli meat. I just need to know, I want to cry!
