I’m just concerned

This is my fifth month TTC. I’m 27, good and healthy but I’ve never been pregnant. No chemicals, miscarriages or anything. Just never. I’m really worried that something is wrong with me as everyone here seems to be looking for their baby #2 or 3, rainbow babies and I’m like... I don’t understand what’s wrong? I always get my period on point, confirm ovulation with opks and temps. Every time I had some checkup at the gynecologist, everything seems perfect. I don’t know what to do 😞
