Has anyone experienced prenatal depression?

I’m almost 14 weeks & since last Wednesday I’ve just been super depressed I only lay in bed and I barely eat or communicate with anyone. I never experienced this with my first but it’s a funk that I just can’t explain…I hate the feeling really & I’m so embarrassed pregnancy is supposed to be a joyous moment and I’m very excited so I’m lost as too why this is happening too me
