what about c!earblue tests I had 1-2 weeks which meen 3-4 and it counted the SAme as my scan

not really accurate no depends how clear it is im guessin. i had an early scan was estimated 6 weeks and when i went for my first scan should have been 10 weeks but i was nearly 13 weeks so not in my case xx

80-90% Accurate I think :)
