Hi everyone,

My partner and I had unprotected sex about 15 days ago and I've taken a test today but I'm really unsure of the result! I've taken tests in the past and the negative has always been so clear. The test was negative immediately after taking it. However this time I have noticed a very faint positive line hours after, could this mean I am pregnant but the HCG is too low, or could it be false? 

I've attached a photo and I'm convinced I can see a faint line (it's stronger on the inverted photo)
