I haven't at all day then I omw to work I got some little burgers and after I finish them I felt find then all the sudden I got nauseous. I'm at work nauseous ass hell so I went to drink some water then my mouth start getting watery that's how I know I'm about to throw up. I went to the bathroom and start gagging because it's hard for me to throw up so after spitting for a little bit I washed my mouth out and hand and went back to work and felt better. I'm like wtf is going on 
I have 2 period calendars the one I always use that's never wrong say I'm 18 days late so then I down loaded this one earlier couple weeks ago it said I'm supposed to start my cycle tomorrow. I hope I do if not I think I might be...... I have a appointment next Friday for a pregnancy test with my doctor. I want to see if I get my period at the end of this month before jumping to conclusion.
