Weird bbt chart?

Juli • Ttc #1 since June 2015. Laparoscopy to remove endo in July 2016. After 6 failed IUIs, we are starting ivf in April 2017!
So my constant up and down temp is really stressing me out! Especially now that I've dropped below coverline! Does this still look normal? It's just so early to have a drop off in temp 😞
