Huge temp drop at 3dpo

Nicole
Is this normal? I have never had temps this low even in pre-o stages. I haven't been able to temp the last few days but pretty sure I am 2 or 3 dpo based on +opk and ewcm. Today was first day I could temp again and was shocked at the low temp. I am also away from home right now but been here almost a week so would expect my body to have sorted out by now. Not experiencing jet lag.
