I work at a hospital so I brought home a couple tests to use because I feel they are more reliable. After about 3 minutes a line started to form.. I figured it took longer to show because #1 they aren't as sensitive & #2 im only like 9 or 10dpo.. The top one is not tweaked but the bottom one is.. AF shows the 24th.. So fx she doesn't.. Do Dr tests have evaps? Share your thoughts..
