Fertility charts

Rachel • After 4 years and 4 miscarriages. I gave birth to our rainbow baby, Olivia, in January 2016. God is good. Since Olivia we’ve had 1 ectopic and 1 miscarriage hoping one day we will have another child like Olivia so she has a sibling.
Hi glow, I'm not able to view my bbt chart properly because the axis only starts at 36 degrees and my bbt has been as low as 35.2. Is it possible to increase the left axis to include 35 degrees and how would I go about doing that? Thanks sooo much
