Yeah time to stop testing. Remember they're only designed to tell you IF you're pregnant, not how pregnant you are. They can get to a point where they will actually start to show negative, it's called the hook effect and could start happening soon so definitely stop testing to avoid that shock and panic.
Thanks both, I think I’m just in a cycle of testing!
My advice would be to stop testing it only adds to the worry, once you have had a positive test and you've told your docs/local midwife you're all good! Once you get to a certain point your tests won't be any darker and you also could have a false negative due to the high level of HCG ❤️
