I'm 7 weeks pregnant. What causes fetal heart rate to drop from 122 BPM to 81 BPM in two days after pregnancy looked great?

In brief: Hard to say

This question is difficult to answer, because we aren't typically measuring the fetal heartbeat over extended periods of time at this gestational age.
Possible technical error . There's not much to do ---> continue to watch the pregnancy. It's normal for fetuses to have cyclic drops in their heartbeat. You may want to consider closer following and possibly an echocardiogram later in pregnancy.
