Just came across a free download, looks thorough enough. Anyone use this online charting service? BTW, I'm new here. I will be charting for a few months or more before we TTC. Just got off the mini pill (POP) a couple of months ago. I apparently conceived while taking this pill almost perfectly for quite awhile, however, it was an ectopic pregnancy. I had surgery, but still have all my girl parts- few! I'm so happy about that.
