pregnant? or crazy?

Okay so due to my periods I shouldve ovulated somehwere between the 27-4 (april 27 to may 4) me and my SO had unprotected sex on everyother day throughout april 27 to may 4. My period should be here on may 15 (tomarrow) my last was april 17. Not sure how long my cycle is however. Ive noticed it seems like my body is hot to the touch, well warm not like extreme fever but slightly elevated. Ive been sweating all night but fine during the day unless its over 75 degress in my house. I had some cramping on my right side on around may 10th. The 11th and 12th the cramping was in the middle and ran down my thigh on the left an right side. I kept having to change the way I was sitting at work because of this.. those same days I couldnt get enough sleep I was super tired. On the 9th of may I was craving pizza and when I ate it I was starting to feel sick, like I was gunna puke.. nothing else made me feel tht way and but only happened tht day. The pains in my legs werent "pains" by the way, they were like twinges. Weird I know. Ive also been getting ALOT of restless leg, all day... for about 4 days now. My stomach is bloated on and off during the day. Ive only been off BC for a little over a month. Oh and yesterday (may 13) I got a weird mettlic taste in my mouth while eating with a spoon ( yes I know there made of metal, ive been eating off them forn years and this is the first time ive tasted them mettlic) this would be my second pergnancyif I am that is... my boobs had sharp pains in the left last night, besides tht just sore to the touch.. I had a negitive home pregnancy test on may 11th. Can anyone help me out?...
