Hi. This is my first month charting, am 36 and came off the pill December 19. Up until last month, my cycles were always 26 days and would last just 3 days. On day 13 this month, my temp dipped to 36.1 and remained that low (from 36.3) for 4 days, when it started to gradually rise. Its continued to rise steadily, and then on day 25 went to 36.7, where it has continued to stay. Im now on day 31. I had all the usual period symptoms, cramping, back and leg ache from days 24-28, but apart from a dull back ache these have all now stopped. Can anyone shed any light as its all so new to me! Thank you x

My understanding is the shift in temperature is when you ovulated, when I temped from day 1 until around day 13 it would be below 36.4 and then after I ovulate it would rise to above 36.4.
What was the temp from day 1 - day 13?

Although on my very first month, I didn’t realise you had to take it before getting out of bed! So it made the readings inaccurate.

Haha oh bless you. Day 1-13 varied between 36.2-36.4.

Ok, yeah so when it started to rise it would indicate you ovulated. If it stays higher when you would have expected you period to start, you could be pregnant. I’ll attach a picture of my chart the month I fell...

Thats really helpfull, thank you. Had a little dip yesterday (36.64) but today back up to 36.6..... Would the dip be a problem or indicate that I couldn't be pregnant? Am waiting until weekend to test (once day 35 passes)

Also, bizarrely have just tried taking it again (just out of cutlriosity more than anything, and its back down to lower than original reading first thing! So confusing!

Your temp is only reliable first thing in the morning, before getting out of bed. Throughout the day it will fluctuate.

As long as your temp stays above 36.4 (or whatever your baseline is - but 36.4 is average) there is a chance you could be pregnant.

You have more patience than me though, if you are on day 28 an early detection pregnancy test should pick up whether you are pregnant or not!

Heres my chart when I got my BFP to compare. Sounds promising for you. little dips are normal

I gave in and took a test. Negative! A little upset to say the least but more confused and worried as to what could be the matter.

Was it an early detection test? It also wasn’t first morning urine, so it would be more diluted!
Maybe wait until the weekend / to see if period does arrive.

💐 I remember how difficult the TTC part is
