Has anyone experienced a significant shift in your BBT coverline - maybe following a pregnancy, miscarriage or for another reason?  Over the years, my coverline was usually at 92.0, then moved a little to 93.0 (pre-O at 96.8-97.2/post-O at 97.7-98.4 with slow rise), but this cycle (and maybe last but I was lazy last month) its at 96.0 (pre-O at 97.2-97.6).  I am confused and surprised at such a change in my coverline. (more details if interested to follow - but that's the gist of my question.)

 

I have been charting my BBT for over 8 years now (except during three successful clomid pregnancies) so I am very familiar with my body and hormone cycles (which are far from textbook).  I have had many changes/improvements to my previously anovulatory/PCOS tendencies following each of my pregnancies (including the onset of fairly regular cycles and a late but ovulatory pattern).  I am now 18m PP, with AF returning at 11m PP.  However, I have had 2 miscarriages since then (08/2010 and 12/2010).  The rise seems to have taken place since the Dec. loss.  Is it just my hormones improving/adjusting - or could it be something else?  Thyroid work in Oct came back fine.  We are getting ready to try again after my next cycle, and I am confused by the fact that my temperatures have not dropped much below my previous coverline (although HCG is clearly at 0 and progesterone had dropped as well).  I keep hoping its just better hormones (my pre-o temps were a bit higher when using clomid, but not like this).

 

Thanks for any thoughts you might have to share!
