Pregnancy & Birth Control: Miscarriage Risk & Pill Safety

Question
upon falling pregnant say the first few 3 weeks is it possible to miscarry after taking the last seven tablets of the birth control at the same time or just being on the pill at all

Answer
The last week of pills are not active ingredients so they would do no damage to a baby.  Getting pregnant while on the pill isn't the best thing to happen to a newly conceived child but considering the alternative it isn't terrible.  As soon as you know you are pregnant you should always stop using anything that might harm the child.  As I'm sure you would.
