I believe I would only be around 3 weeks, but I'm showing signs..

and weirdly I have hives all over my thighs, I went to the doctor and they told me they dont know what it could be from. I didnt change any of my cleaning products or anything. I didnt even change my eating habits or eat anything new. Plus I've never had them before so Im a little weirded out, and the med. that I'm taking for them ( two kinds) isnt helping one bit.

My breat are sore.
Its sore during sex.
Vagial discharge.
Hungrey all the time.
Sleep around 15 hours a day the pass 2 days.
I feel sick to my stomach sometimes.
Cramps.

What do you think?
I did take a test today and it said neg. but I believe its to early.
