Occasional jumps and drops are within normal. If you find the majority of your readings fluctuate significantly consider any of the following factors that can contribute to erratic readings:
- Taking readings outside of a consistent 2 hour time frame.
- Using different positions for readings (some standing, some laying down)
- The moment during the reading.
- Not inserting kegg fully
- Taking readings too soon after sex
- Significant stress, change in daily routine or travel
- Inconsistent hydration
- Illness or infection
- Presence of foreign substances like vaginal medication, ointment, or lube.
