43 yo new to charting and confused

I am 43 yrs old and ttc for the first time in my life. I waited for the right person to come into my life...it just took longer for him to arrive than I had hoped. 😉

He two months ago he had a vasectomy reversal which everything says takes many months (ugh) to get up and running fully and he will have a sperm analysis next month.

That being said, we started trying (yay fun practice) and I started learning how to chart this month for practice.

Maybe it is because I am new to chart or maybe I have a wonky bbt because of my age, but my chart looks different than any of the ones I’ve been seeing posted in the last couple weeks. Some guidance would be appreciated ladies to understand my chart because it is full of peaks and valleys.

I went to a fertility clinic in 2016 and was told that with my lh levels using opk wouldn’t be accurate so I am not using them. Going on mucus and bbt.

Any guidance & input is appreciated!
