All of a sudden hating the car??

Hey ladies, my babe is almost 20 weeks and as of the past few nights she HATES the car. She has been the most chill relaxed baby and out of nowhere she screams bloody murder when in the car. I'm wondering if this has anything to do with the 4 month sleep regression??? Shes been super needy the past week and will cry if she doesn't see me right near her. Please tell me it's just a phase 😭😭 I've never heard my baby cry like she did. The only other thing I can think is that it was nighttime and super dark and it freaked her out??
