worried about an sti

No judging please I already feel disgusting.. well Im going to be treated for chlamydia in a days time (earliest appt. available) after going for a routine check up.. I'm really worried it's going to affect my fertility in the future if it hasn't already. Has anyone else ever contracted it and gone on to have babies? I can't help but worry😔 And before anyone says I should of used contraception I did it split and that's how I got the infection. Thanks
