Took a test over two weeks ago and today

So I haven't had period since July 28th and I'm irregular but I never ever skip a month. My period normally starts by now. I took a test cuz my boobs have gotten bigger slightly but noticeable. The nipples are sensitive and hurt. I've been really emotional and hungry alllll the time and eat a lot. But if I Dont want or my body Dont want the food I revolt it and get nauseous. Idk what to do. I'm so confused and really disappointed that the test this morning was neg. Could it be to early?? I had light light spotting over a week ago. For only 3 days. Any advice will be helpful. Should I wait a week?? Couple days?? Is it to early? Is the test wrong Idk I'm sorry I just was so excited and anxious cuz I thought it'd be positive but it wasn't so I'm really upset and my spouse is to...
