you should go to the doctors asap!!! :) sounds ike you may be pregnant. You will want to know if you are pregnant before anything and you want to make sure the baby is safe and healthy. But it sounds like you are pregnant. Congrats! and Good luck.
The best thing to do is to go to your doctor and have them let you know that way you know the gender for sure and there is no if ands or butts :) good luck!
