My period is late but all my physicalsymptoms  can be explained with other reasons than being pregnant. Reciently my fiancé and I got in a fight so I'm not sure I could do this alone. But my symptoms are
Hot flashes- sometimes I feel like my skin is on fire have my friend feel my for head and its normal to her but to me I feel like I'm bunting from the inside out 
Shaky- weak and trembly 
Vision issues- my eyes are bad enough bout over the last two weeks its like my eyes have gotten horrible!
Headaches- that knock me down intense and crazy fast 
Car sick (which I've never had)- can't ride the bus anymore without feeling like I'm going to vomit everywhere and I get more dozy in cars never been an issue before.
