Temp drop 6dpo?


My temp has drop from 97.916 F (36.62C) to 97.7 F (36.50C) 6dpo is this a good sign if my temperature goes back up or is it still to low or do I need a lower temperature dip than this? Any advice please if you have been through similar? I've had minor cramping (twinge/pinch feeling) the past few days and lower back pain
