Like the other ladies said, other things can delay a period. Stress, hormone imbalance, illness, sudden diet/weight change, PCOS, cysts etc can all delay a period.
Wait another week, and if still no period, then re test with first morning urine. If that's negative and still no sign of your period then see your doctor!
Hi. I would wait a few days like the above poster said. You are about one week late based on an average cycle length and we can have late periods for any number of reasons (stress, hormones, etc.). So, wait another week and try another test.
good luck
You could wait a few days and do another hpt or call your doctor to have him order a beta hcg, they are more accurate. If pregnancy test is still negative something else is probably going on. I had a cyst that delayed my last period almost a month. I wish you the best of luck.
