Possibly pregnant?

Vannesa

So I went into urgent care today with the symptoms of nausea head ache tmi but diarrhea and fatigue. I never actually threw up I only dry heaved. I am a week and a half late on my period I took a pregnancy test last week and one today at urgent care both negative. They still then think I am pregnant so they are taking a blood test and I won't get the results until Wednesday. They prescribed me prenatals as well as nausea medication for someone who is pregnant. Any ideas?! I feel so sick.
