A week late and negative tests 😢

I am so confused! I am a week late, and tested on day 4 of my missed period and it was negative. I have had a ton of symptoms in the last few weeks as if I am pregnant... I am super fatigued, lower abdomen cramping, nausea, crying at dumb things that I never have cried at before, for the last 3 weeks I haven’t been able to resist anything with vinegar (salt and vinegar chips and popcorn, sauerkraut, balsamic vinegar dressing on everything, pickles) and I just feel uncomfortable.... what do I do?!? I keep getting my hopes up and then test and it’s negative month after month. Does anyone else have this experience, or has anyone ended up pregnant even when the test says negative???
