Feel like I'm going to throw up

Sara
So I'm nauseous I would be about 3 or 4 weeks depending on when we conceived if I'm pregnant . I'm scared to test because I almost don't want to know until later so I don't get my hopes up again. I kee getting smiley faces on my OPK
I know it Could be old hormones but I also haven't felt his way all month until the last few days and am having this pulling - meddling cramp twinges for days since I had pink spotting last Sunday . 
Nausea started last night -
Anybody else feeling this or postponing testing because they are afraid of knowing too early ??!!
