BBT: fallback rise or later ovulation ?

Question

Hey does this look like a fallback rise in my bbt? I assumed i ovulated on cd 13 bc i had a 0.7 rise in bbtc but the next day it fell. Since then, my bbt has remained above my cover line. Does this look like i ovulated on cd13 or cd15? I didn’t have as much ewcm on cd 15 as i did on 13. Also, i had mild cramping on cd 13

Answer

Cd15 looks like ovulation day to me.
