Could I be pregnant?!?!?

Hello All! I have enjoyed reading yall's posts and decided that I too would like to put my situation out there and see if anyone has any suggestions! My husband and I have been trying to conceive for about a year now. He had a vasectomy 8 y ears ago and had it reversed a year ago. The first reversal did not work so he had to have it done again but the doctors were optimistic that this time the tubes should hold together. I have not been pregnant yet but have been having some odd symptoms lately which are leading me to believe I should investigate further!

First of all, I was scheduled to have AF April 30th which I did however it was VERY light and VERY short. Not at all what I am used to. After doing some research, I found that there can be very light bleeding which is often mistaken for a period but it is not a period. I have also been very tired and extremly bloated which is unusual for me. I have an apparent "belly" and people are starting to notice. My boss has joked with me on several occassions about "gaining weight" as a method to try and get me to admit I am pregnant but as of yet I do not know if I am or not! I am getting extremely dizzy and moody as well! I took a pregnancy test after I was done bleeding and it came up negative. I have a dr. appointment next week and will get a blood test done but I am so anxious and want to know if anyone else has had symptoms like these!

We very much want a baby and are hoping to have one soon. I know that my hopes of becomign pregnant are sort of swaying my emotions and my mind into believing every little thing is a sign of pregnancy but you never know!
