Clear blue said 2-3 weeks and now says 1-2

I'm fearing the worst here. I recently had a chemical pregnancy in June of this year and believe I am having another one. I took blood test yesterday and the results came back 261. I will go back in tomorrow to retake to see if it has decreased or increased. I took the clear blue on 11/17 it came back 2-3 weeks. I took another one yesterday evening around 9 pm and it still said 2-3 weeks pregnant. I decided to take my last clear blue test with my morning urine. I woke up around 4 am to pee (been having to go a lot!) and took the last test. This one told me that I was now 1-2 weeks pregnant and I was devastated. Seems like another chemical pregnancy. According to my last period I am 3 weeks and 5 days today. Anyone else ever had clear blue weeks decrease on them?
