can someone check my chart?! +ve then -ve preg test

[PontyGirl]

I have PCOS and my cycles are irregular so I chart and usually my charts show a clear shift. This month is a bit of a mess and so I changed fertility friend to the 'research' mode and it came up with the below. So I did a tesco digi with FMU this morning which came up as 'pregnant', but all other tests later on (cb digi and tesco normal) are BFN.

I don't trust the research mode. Just putting it out there for some interpretation. My LP is usually 12 days if that helps!

I used ff but didn't have pcos so no use on that front, but if you are in very early stages of pg it would be quite common for a test to only come back positive using fmu. Sounds like you are pg!

I agree with Iggi. False positives are unusual. HCG levels are usually higher in FMU so it may be that you are in the very early stages of pregnancy, and the HCG levels are not yet high enough to get you a positive result on your later tests. I would test again in a couple of days.
