No period after stopping the pill........

[marriedgirl33]

I started taking the pill on February 17th, the day after my last af started. The last bc pill I took was on March 1. I had unprotected sex with dh quite a few times since then and now my period is late. I've also been nauseous after eating certain foods like dairy foods and mac and cheese, I actually wanted to drink milk-even though I got nauseous after I did so, the only things that I can stomach are goldfish, chicken, rice,green peas and cereal and I felt tired and worn down as well as having sore bbs. How soon should I take a pregnancy test and should I ask the doctor to do a blood hcg test as well? The gynecologist that I saw on Monday refused to do a blood test.
