Patience is truly a virtue

It all started about 2wks ago: peeing in the middle of the night was keeping me from sleeping. I woke up almost every hour to pee. Then I craved beef jerky; so much that I could taste it in my mouth! I haven't had that since I was 10 or 12yrs old. I find myself sleepy during the day and breast extremely sore and nips poking out more than normal. My body temp has risen over the past few days and my skin's sensitivity has increased. I get nauseous sometimes if I haven't eaten,afterwards I feel better. Odd but I've craved water as well, feeling so thirsty all day. I have had constipation and bloating. I have taken 2tests which say negative. Im probably still too early to test positive but I can't help feeling anxious. With all these changes happening, I just want to know for sure. I have 3 days till I am suppose to start my cycle. All this waiting is killing me. Usually a week goes by quickly, but when waiting for something like this it seems to go by soooooo slowly!!!
