Try to get pregnant

Hey ladies! Me and my husband have been together for 5 years and have only ever used protection twice. We are really wanting to have a baby but idk what to do. I’ve tracked my ovulation and know the right time to do it but no luck. We would go to the doctor to even see if we are able to have kids but we don’t have insurance. Is there like an at-home test we could take to see if we are? Or is there something I need to do? I’ll take any advice!!
