Has this happened to anyone else?

I was 1 day late so I took a test, I got a very faint positive. I then took 2 more tests including a digital one that said pregnant.  That was all on Saturday. Today I took a test just too see if it would be darker, but the 2 tests I took this morning were very very faint positives. I went to my doctor and she said the urine test did not come back positive (she said that happens sometimes, people get positives at
Home and not yet at the doctors because it's so early) she took blood but I don't get results till Wednesday and I'm a little worried. 
Is there a chance it's too early for the blood results too?  
And has anything like this happened to anyone else?
