This is actually called dysgeusia, which happens due to estrogen fluctuations. My doctor told me it's very common in the first trimester and usually goes away on its own.
I know how annoying that constant sour taste can be when you are already dealing with so much anxiety. Please hang in there, your body is doing a wonderful job growing this little life.
I had that horrible sour taste throughout my first trimester, but it slowly vanished. Even after my recent C-section recovery, looking back, those early weird symptoms seem so small now.
It's mostly hormonal shifts and sometimes mild acid reflux causing that sour or metallic taste. Keep sipping water, chew on some mint leaves, and it will settle down.
It's a classic early pregnancy symptom caused by hormones, but check with your doctor if it makes you too nauseous to eat. They can suggest safe ways to manage it.
