Advice for ttc

hello all! I’m 19 and hav even ttc with my fiancé for 7 months. i’m transgender and was on testosterone for 2 years and i stopped it last year. i was on birth control until i started ttc and didn’t get a period until 2 months after that. i didn’t even start ovulating again until about 4 months ago. i have some health issues, arthritis in my spine and a few pinched nerves, so i’m always in a bunch of pain, specifically in my back. i really want to be pregnant. i actually cry when i take a test and it’s negative. but because of my issues, i’m not sure what pregnancy symptoms are actual symptoms of pregnancy for me. should i regularly test for ovulation since it changes every month and regularly test for pregnancy or should i just try to clear my head and let it happen naturally?
