I took 2 pregnancy tests on Sunday, one a clearblue and one a strip test and both had faint lines, my period was due last Thursday and a had a very light bleed that didn't come to anything when normally my periods are that heavy I have to use night pads during the day, it was this that prompted me to take the test. I took another strip test yesterday and the line was a little fainter than Sundays and then today the line lighter still, I have pregnancy symptoms like sore boobs and nausea but I'm worried about what these tests could mean, could it be a chemical or an ectopic even, has anyone had experience of this?
