I have been feeling sick, tired, getting headaches, somewhat of back pain, changes in my boobs, been going to the bathroom more often and change in taste of food. I took 3 home pregnancy test and they all came out negative. What should I do? Why do I feel the way I do if I am not pregnant?

I took 3 home pregnancy test and it came out negative. I have the early symptoms of pregnancy. Each day my nauseousness keeps getting worse. I been feeling tired a lot lately. Even though I have early pregnancy symptoms, it could also just be PMS symptoms, according to some other people.
Lately I have been feeling sick, tired, getting headaches, somewhat of back pain, changes in my boobs, been going to the bathroom more often and change in taste of food. Apparently, they are signs of being pregnant but I took a first step pregnancy test today and it was negative. I don't know what to do.
All this started when I had a this red bump and it hurt like a b**ch. So I searched for some answer but all I'm getting is that it's apart of early pregnancy sympthoms or cancer.
So yea that's my story. :/

Simply, your two questions have been merged here. Stay tuned for replies :)

Why not make a doctor appointment? Seems like that would tell you what you need to know.

I made a appointment to the gyn for Saturday. It's driving me crazy on not knowing.

You could be pregnant, you could be not pregnant, there could be something hormonal going on because of that red bump, there could be something hormonal going on because of something else. Unfortunately, since we can't do a blood test (yet) or examine you via the Internet, you're going to have to take a deep breath and wait until Saturday. I know, I know. Waiting is awful.

Please let us know what you find out.
