Kinda stupid question.....

I take excedrin super strength every morning bc I get caffiene withdrawal headaches bc I quit drinking mt dew like crazy cold turkey.. If I'm TTC and I get pregnant, will the excedrin be a risk to the baby or anything?? Will it somehow affect the pregnancy tests.. I'd stop taking it but my headaches turn into migraines if I don't do something about it and I really don't want to start drinking mt dew like crazy again.. I'm sorry if that sounded stupid but..
