Hi girls, I've recently had some weird light yellow discharge, then earlier I felt something 'come out'. I went to the toilet & there was a streak of light orangey coloured blood. What is going on? Sorry for the graphic image! I did a pregnancy test last week & it was negative but I looked the next day when taking out the rubbish & it had a faint line. I am putting it down to evaporation. I have since done another pregnancy test & it was negative. I have a vague ache in my lower back & occasional twinges of pain in left side of stomach & have been sick once the other night with no explanation as to why? Please can someone advise.
