Abnormal Temp Drop at 7 DPO?

Ignore the gap. My puppy chewed up my thermometer so I had to get a new one. Also my cycle is super long this time, I ovulated late on my last cycle of clomid. Anyway, I had this temp drop this morning. I took my temperature at the same time that I ALWAYS do and went to bed the same time I always do. I even took my temp a second time (right after the first) just to double check and it was the same. Why is it so low?? 😓 I am 7 DPO.
