I am worried bc my LP has been seeming to get shorter... As in the last 3 months I have been spotting a few days before my period.  However she is always on time and   comes with atrocious cramping and heavy flow.  Nothing yet.  I fear, as I am 34 and my cycles have been changing, that I may be implanting but our bean won't stick due to possible low progesterone.  Normal Paps and blood work a couple months ago... However she did not check my progesterone.  I am now currently looking for OB/Gyn that I actually like and will have our insurance back in November!
