teen Baby fever 😩😩

So i don’t know if this is normal but every month like clock work starting at about 9 days before period through my period I have EXTREME baby fever like all I want is a baby and to be pregnant and i have a high drive. WELL i don’t even have a boyfriend i’m only 15 and i don’t know how to deal with it any more. it’s gotten to where it’s a burden and i fall into some sort of depression every month. I don’t know if it’s normal because everyone i’ve talked to doesn’t go through it but It gets SOOO BAD! Im homeschooled and have a job and saving so I could afford a baby cause that’s why everyone says it would be a bad idea but I have money. so i could use some advice or words of encouragement or ways to help
