Post-Birth Control Hunger & Side Effects: What to Expect

Question
I've just recently stopped my birth control pills after being on them for a little over 4yrs.  I had my period last week but didn't start a new pack of pills on Sunday (1/14).  Since being off them I feel constantly hungry almost like I do when I pms sometimes. I am also taking Trim Spa to try and lose weight, so Im not sure if this is the culprit to increase in hunger.  Can coming off birth control cause an increase in hunger? Are there any other side effects to stopping the pill?  

ps. My husband and I are going to try to conceive that is why I got off birth control.

Answer
some hormone changes can cause appetite changes, but birth control pills on or off have no calories.... the weight gain or loss depends on what you eat..... other side effects...... any problems you had prior to birth control pills, like heavy or painful periods or PMS symptoms can come back......
