It was first response early result... I am almost positive I am late for my period too by a few days but I am guessing at when my period was last month. I may be off a few days.

Hi--when was your last period and has your period ever been late before?
Customer: replied 1 year ago.
Yes.
Customer: replied 1 year ago.
I think it was around June 18,2015.and it has been late before
Customer: replied 1 year ago.
Also, my husband had a vasectomy 10+years ago so we didn't use protection . I am probably being paranoid.
Expert:  Dr. Chip replied 1 year ago.
OK Then it's been long enough that the pregnancy test should have registered positive if you were pregnant. That, and given your husband's vasectomy, there's no way you are pregnant
Expert:  Dr. Chip replied 1 year ago.
Let me know if you need any more information please
Customer: replied 1 year ago.
So vasectomy failure rate is rare?
Expert:  Dr. Chip replied 1 year ago.
Very rare but not zero. However, given your last period date, you should by now be registering positive on a pregnancy test if you were pregnant
