Very confused

Veronica

I am feeling at such a loss here. We started trying to conceive baby #2 last month, so this is the first cycle. I have been tracking my periods for a while now and for the last year since I started, they come on the exact day the app predicts. I was expecting AF on March 3rd and still nothing. Countless pregnancy tests have been negative then I went and had my blood drawn and it came back negative too. With my first I tested positive the day of my missed period, it was a very clear dark line. This time around I feel pregnant I have constantly been feeling sick and the smell of raw chicken (I cook chicken almost every night) has been making me gag. I feel so pregnant but I can’t get a confirmed result. What could possibly be going on?
