I tested on 9dp5dt on a medicated FET on having very light spotting and cramping, the line was lighter than the control line but "positive".
Today is my OTD and this morning the pink dye got fainter and was slower to appear.
Although it turned darker around 10 minutes-ish, the test says results obtained after 10 minutes may be invalid. The cramping and spotting are still happening.
The previous test was done in the evening though.
I'm now left to second guess until Tuesday when I will get results from the Monday hCG (to be done).
Has anyone experienced inconsistent line colours and then gone on to have an ongoing pregnancy?
Thanks! xxx
