Baby?

My husband and I have been trying to get pregnant since March 2010. Since I was on the pill for 16 years I did not have any expectations of getting pregnant right away but my periods have always been very regular. My last period was due 8/31/10. I've never been more than a day or two late so by Friday 9/3 I went out and bought a pregnancy test. I started having symptoms Thursday: nausea, fatigue, frequent urination, sore breasts, crampy feeling. I tested Saturday (9/4/10) morning with first urine. The test was negative and I was so disappointed but the sympoms still did not go away so I tested again on Tuesday (9/7/10) with first urine and AGAIN a negative result. So a week now has gone by without a period and the sympoms. I am so frustrated. I'm going to wait until next Friday and if I haven't gotten my period by then I will test a third time. In the mean time I made an appointment with my primary care doctor for 9/13/10. Hopefully by then I'll know something for certain with the HPT.
