Thoughts on drinking coffee...

I recently found out I’m pregnant with baby #1 so this is all new to me. I am a big coffee drinker, that’s the first thing I do in the morning, but when I found out I was pregnant I completely stopped. I’ve been extremely tired, been having headaches, and I want a hot cup of coffee SO badly. Some people say to not drink coffee at all and some people say they drank coffee all through their pregnancy. What are your thoughts? Has anyone swapped it for something else in the morning?
