Is it Normal?

Okay so usually I’m like a real horndog😭(when your man has a good🍆 it’s okay😛🖐🏾) Currently I am almost 5weeks pregnant and since I’ve been...I haven’t really been feeling sex .🤔usually I would be so turnt on panties just wet and stuff but I haven’t really been wanting to have sex🤷🏾‍♀️ and my fiancé asked is it him or anything NOT AT ALL & There’s No Other Man/Female Either I’m Just Not Interested😐. Has anyone else ever experienced this feeling during pregnancy?
