Early pregnancy symptoms

What were your first initial sign of pregnancy and when did it occur? I'm wondering because I think I'm just over 2 weeks along and I'm very emotional (bawling constantly even about cake and while cooking rice) naseaous and extremely gassy as well as odd pressure on my pelvis . And I'm wondering if anyone had an experience like this to ease my mind. I took a test 2 days ago and got a vvvfl it was on a blue dye test. My boyfriend has a gut feeling I'm pregnant and he had an odd dream a few days ago about him having a boy and he noticed it had my eyes (it was very descriptive) any help would be great!!
