Trying to get pregnant

Hello everybody, I’m trying to get pregnant for 8 months now and nothing🙁, I’m a little bit frustrated because both me and my husband we did tests and everything seems ok. My cycle length though is getting longer and longer, this month was 32 days. I’m 33 years old and this never happened in my life, my period was always on time and my cycle length was not longer than 27 days. I don’t really know when I’m ovulating but we’ve been trying hard and nothing. Any held or suggestions would be really appreciated, thank you.
