I need some support y’all, please I’m so heartbroken

My AF is two weeks late and all I’m getting is negative test results. I have symptoms so I was so sure I was pregnant. I was so excited. And with every negative test I lose hope and I don’t understand what is going on with my body. How much longer do I keep this up? Should I just make an appt on Monday? Is it possible to have a chemical pregnancy and still miss a period? I have 3 more tests left to take. I’ve only been taking the $0.88 ones. And a couple FREP in the beginning. I thought I’ve seen some vvvvvfl but then the next test will have nothing. This rollercoaster is too much. I feel like I’m really snappy towards my husband and that’s not fair. Any advice and kind feedback is greatly appreciated.
