This is my first month charting my BBT so I’m looking for some help understanding it. Today I am 12DPO/CD26 and my period is predicted for 01/26. Last month was my first cycle off of birth control and my cycle was 26 days with cramps starting 3 days before my period. Last night I had a small amount of brown CM and this morning my temperature dipped, so signs are pointing to my period starting soon, right? The only reason why I’m questioning is because I don’t have any cramps at all yet and my bedroom was unusually cold last night, like I had to sleep with extra blankets and a heating pad so I’m wondering if the temperature could have affected my BBT? Is pregnancy totally out of the window at this point?
