Pregnant not pregnant that is the question?

Tatiana
Hi guys! I am new to this but I know this may sounds peculiar but we had unprotected sex (where my husband doesn't pull out)Sunday as our first day of trying and by Sunday afternoon/evening I felt peculiar/ this feeling has lasted. I feel sick and dizzy. My urination has increased to the point I am waking up at night and my pee smells peculiar- called the Dr and was adviced to take a test- however I know it would come back no as its way too early but something is different and I just don't feel right. 
The point is do the symptoms sounds familiar to anyone or is it too early to know and should I push to be checked out for something different? 
Thanks everyone in advance- i appreciate all responces. X
