Does being overweight dramatically effect how well the pill works? Do you have a better chance of getting pregnant while on the pill if you are overweight or obese? I am just trying to figure out if continuing to take the pill would be a good idea for me. I am overweight. Also, I have a really stupid question, but does taking the pill at a different time really effect it that much? For example, sometimes I forget to take it, so I will remember a few hours later and take it. Is that really a huge deal in its effectiveness?
