Worried

Hey. I had a faint line yesterday but ive just gone to toilet and had blood when I wipe. Only a very little bit. Super light in colour. I havent got an appointment to offically confirm im pregnant until next week. This is the only stick (out of 4 -3 boots 1 FR) which showed a line. What should I do? Is bleeding ok? Having tightness in abdomen too..not like period cramps, just tight and comes and goes. Im about 5 weeks
