I have been having IUI and was told to test yesterday day 14

I tested today day 15, there are lines there but so faint. I am aware when I ovulated due to scans so I know my dates. I have been pregnancy 3 times before and had such strong lines at this stage.

The clinic told me to retest in a few days or ask my doctor for bloods if still light.

The blue ones came up right away, I know blue is bad. I have done more pinks and they are all the same sort of level of colour.

Is light really a bad sign?

More pinks

I would say give it a few days and test again. Sometimes the lines take a bit longer to show but not for any sinister reason. I've had friends who had to wait a couple of weeks after a missed period before even getting a faint positive. And my mum never got a positive pregnancy test through her entire pregnancy - she only found out through blood tests!

FC in a few days it will be much darker for you - but they are def positives x
