Pregnancy usually stops menstration too. And causes weight gain.
Whatever is going on, a doctor needs to be consulted to be sure it's something benign.

here is the update. i went to see the doctor today, he is gonna give me a complete checkup in two weeks.

what do you guys suggest i check up on? and what kind of blood test should i request?

oh and.... i don think i am pregnant.... i cant be.... unless i am the next virgin mary! ahahaha

Silence -- once you are forthright with your physician about all your symptoms and concerns -- let he/she decide which tests are appropriate. That is what they are trained to do.
Best of luck to you!
