I have baby fever baaaadd !!!

So I’m 16 and I know me having a baby right now would be a bad idea. And I thought that when my cycle ended the thought of having a baby would fade... but it didn’t! Idk what to do I physically can’t control myself I’ve withdrawn my self from having a relationship with anyone till it fades because I don’t want a baby! But I do ? What’s wrong with me will this feeling fade it’s so bad it makes my ovaries ache when I see my baby cousin. I don’t know what to do ahahaggahagagah!!!!!!!!!!!!!!!!!!!!!!!!!!!
