Coffee in first trimester?

Mei • I'm 29 years old, married to my best friend. Can't wait to be a first time mommy <3
Any ladies out there drinking a cup of coffee in the morning in the first trimester? I used to be a two cup a day coffee drinker, doc apt isn't untill ten week mark and I'm almost 6 weeks. Can I still drink one cup in the morning as long as I pass on other canine sources through out the day?
