Will i ever be pregnant?

Hi well i have a problem.. Im 17 and my partner and i have been trying to have a baby (i know youll say i might be too young but me and my partner are financially stable and his fam already wants a grandchild) we’ve been trying and we even did it 5 days straight no protection and i dont understand why i dont get pregnant. I just really want a baby and im afraid there might be something wrong with me. What do u think i should do? Im scared.
