Vomiting at Midnight

Just got woken up with the most annoying sickness in history. But what does it mean? Is it the sign I'm hoping for? I've been wondering whether or not I'm pregnant for the past week and a half. I've taken four tests, all negative with the most recent being Tuesday. But I'm also coming off of the implant so I have no idea when I'd get my first period. Up until the past couple days the only signs that I could be were peeing all the time and having a little pink spot that may or may not have been implant bleeding. Then I started getting the other things in mild forms, backache, headache, moodiness. And just a few minutes ago I got to go through the best symptom you can have. I say that very sarcastically. Of course I could just be sick. My child has vomited and had diarrhea this week. So who knows. I'll test again in the morning.
Just wanted to rant a little about what's going on. Thanks for letting me share!
