Help Please- what could this mean?

I had almost positive/positive opk on CD13 and a very strong opk morning of CD14. Last round and first round of clomid (50mg) prepped my body for ovulation (had Oh surge) but then didn’t. This round was 100 and I had all the signs (temp increase, very positive opk and ovulation cramps on CD14).

Was feeling so great but as you can see last two mornings we’re low temps- does anyone have an idea what this could mean? (I started tempting later because while taking clomid it causes your temp to be off-these we’re CD 3-7)
