Does anyone have erratic temps like mine with a dip In 5 and 6dpo

Charlene

I work shift patterns so it's very hard to temp every day at the same time. I do my best and temp as soon as I wake. Our timing was pretty bad this month as other half just didn't feel upto it. I somehow hope I manage to get 2 pink lines for Christmas. Here's my chart as from today I'm currently 6dpo. It was freezing this morning only 1degree celcius outside hence I'm thinking that may be reason for. Low temp? I temp orally too and was congested last night so I'm hoping it was because of that.

I know my mouth had been open
