Trying to conceive

Shakira

So I’m new here an I’m only 23 I’ve always wanted to be a mom more than anything in this world but yet I’ve never been pregnant My cycle is very regular I ovulate on time an I’m really quite healthy but I’ve been trying for a while for about 2 an a half years an nothing is there anything I should do? Also my doctor says everything is ok an healthy but why do I not have a baby??
