baby fever help please

so I am 18 years old, a senior in high school and I have the worst case of baby fever ever. I keep seeing pregnant people everywhere and little babies everywhere and I get this really intense desire to get pregnant. I was hanging out with my guy friend the other day and I literally just blurted our “omg get me pregnant” out of NOWHERE!! What is that??? I am way too young to have a child right now and I definitely could not take care of a child right now so why am I feeling this way?? And how do I NOT feel this way??
