Ok so I’m 7 days late I took a digital pregnancy test after 5 days late and it said not pregnant I’m 36 yrs old and last month my period was longer than normal should I re-test or worry something is going on with my body. Normally I’m like clock work every month it comes when it’s suppose to no matter what the last time I had a missed period I was pregnant and I have a 10 yr old now but when I took the test it was positive right away so now I’m confused
