So I have taken multiple tests. First 3 were positive. Generally they were just cheap strip tests but one was a clear blue early signs test. I took another today to ensure the lines are getting darker as they were all faint (except clear blue) it was negative! It freaked me out so much. Went out got another clear blue and its positive. Has anyone else had this? I did read that if urine is diluted, that may give a negative. I had drank loads of water so urine was pretty much clear. What are thoughts as I'm worrying a bit!
