Pregnant or not?

So I took 5 pregnancy tests total.. I took the first one 4 days ago that had a vvvvfl. So then I took a FRER and it had a faint line as well. Well the next morning just to be sure I took another FRER and it came out negative. So I took ANOTHER one the next day and it had a faint line but darker than the first 2 tests. But I took one more just to be completely positive and I took it 2 hours after the last test and it came out negative??? I'm so confused.. What do you ladies think, pregnant or not?? Here are the pictures of the tests that came out positive.
