Metallic taste in my mouth

I woke up this morning with a weird taste and when I went to drink a glass of water it got worse. I noticed it a little bit yesterday but it went away before it really bothered me. I know they say it is common among pregnant women but it's really like ugh especially when I drink water and I like to drink close to a gallon a day but today I know I won't be able to. Hoping this is a first trimester thing
