Hcg strips to regular tests question

Miranda
For those that use the strip tests, when do you go get a frer or clear blue?  I keep thinking I see faint lines on my hcg strip tests and I'm tempted to go get a frer but I don't wanna waste money...sigh....I'm like a week late on top of a skipped months period...idk 😥 
Any thoughts from you ladies?
