Hello Ladies

I haven't had my period for a while yet. My last one was on March, 1st. And from March 8 till 29, I went to visit my family in a different state, away from my husband, so there was no relationship. But since I got home, on March 29, there has been contact. I was suppose to start my period yesterday, but there is no sign of it at all.

Is there any chance that I might be pregent? I am afraid if I would take the test that it would be negative and disappointe me.
