Chart:


What we've learned in this cycle is that ferning during the luteal phase does not necessarily indicate pregnancy. It appears that I just had random estrogen spikes on 9 and 11 dpo. I took a pregnancy test at 13 dpo to check for any trace of hcg, even though it was already clear from my temps that af would arrive at any moment. My menses started later that day. Also this cycle I had very few symptoms. This is probably due to the lower temperatures / progesterone levels compared to previous cycles. My analysis? Probably both estrogen and progesterone levels should be elevated in order to indicate successful implantation.

This cycle lasted only 24 days, which is shorter than my usual 26 day cycle length. Maybe the egg was not viable. We don't really know though.
