I have been trying to conceive for 2 months now after being on birth control for several years. I tracked BBT for only 1 cycle and Fertility Friend website said I ovulated on Day 16. It also said that my luteal phase was 11 days and my cycle length was 27 days. Just wondering if my luteal phase is normal and if I should draw a conclusion that after only tracking 1 cycle that it will always be 11 days all the time or can your luteal phase change after several cycles? Also are there any ladies out there who have gotten pregnant with 11 days luteal phase?
