Pregnancy Test faint & 2 Days Late Help!!!!!!!?

I have just done a home pregnancy Test and it was faint LMP 10th Sept.Am I really pregnant or can they sometimes be misleading. I have had 1 ectopic pregnancy & 3 miscarriages.I have all the normal signs & symptoms of pregnancy plus i am 2 days late & my cycle is like clockwork. Has any body ever had this happen? Usually when i have been pregnant before the test showed really clear at this time.
