This is a common question when you are using ultra early detection pregnancy test strips and one that can cause a lot of heartache. The photo graph below was supplied by a customer asking this very question. In fact when we first looked at the photograph we could not see any line at all.
Our advice would be to ignore a line as faint as this and count it as a negative. Wait 48 hours and repeat the pregnancy test using a first morning urine and see if the line is any stronger. Alternatively you could try using a digital pregnancy test as this does not require the interpretation of lines.
We have recently heard about an online trend for digitally enhancing faint lines on pregnancy test strips to make them look more positive. This is not a good idea and will only lead to false hopes. The faint line that you are seeing me just be the test medium that is embedded into every test strip. If you digitally enhance this it may look like a positive, when it is in fact a negative. Some people mistakenly interpret these extremely faint lines as false positives when in fact they were negative.
What we are looking for is a BFP (Big Fat Positive ) and this should be obvious to the naked eye. You should be able to see it clearly and it should not require a magnifying glass or digitally enhancing. It should resemble the Control line that is very clearly visible on this test strip above. As the pregnancy progresses the test line will get stronger in colour as more pregnancy hormone is present in the urine.
