Thanks for your query.
I read your query and I understand your concerns.
It is normal to have delay for a week. It does not necessarily means pregnancy
. The signs what you have are suggestive of menstrual cycles occurring. You might get cycles in a day or two. Take some antacid
tablets for heart burn.
I hope I answered your query. I will be available for any followup queries you have.
