Ttc for 8mos help!

Jennifer
Hey everyone, 
​       I am 30 and have been ttc for 8 mos or so now. I have not had any luck. I have tried opk and a few apps, I just got preseed bc my cm is usually minute and my bbt is all over the place one day 95 and then 97 the next so I gave up on that. Does anyone have any advice on what to try that has worked for them?
