Pregnant or stress

Robyn
As of today I will be 5 days late. Sadly my husband passed away a week ago. Didn't really keep count on sexual activity through ovulation but pretty sure it was on atleast 3 days during. Obviously has been a huge shock to have lost him, I'm 22 and periods have been pretty regular (give or take a day) over the last year, discharge is white. Am absolutely petrified of taking a home test. Could it just be stress?
