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
