Unexplained fertility

A few years ago I was told I had unexplained fertility and literally just told me to lose weight and stop smoking 🙄 I was 10 stone back then we’ve been trying for 10 years to get pregnant I’m 28 now and still nothing... it’s getting me down and I don’t know what to do! They told me I could’ve had clomid but because I sometimes ovulate and sometimes don’t then I can’t take it as it could do damage 😭 anyone else in the same boat
