Small update...

Small update since my last post.  I finished the 10 days of provera (last pill was on February 24th), and I started my "day 1" of a normal menstrual cycle on February 28th.  I called into my regular OB to schedule the saline ultrasound as planned, however there was no availability within the next month between him and the radiologist on site to do it.  So in order to stay proactive and avoid and entire month at least of getting nowhere, I phoned my fertility doctor hoping she could squeeze me in.  She was able to schedule the procedure with her team, and she also wanted me come in for my "day 3" of blood and ultrasound (March 2nd).  Blood and ultrasound came back later the same day completely normal.  She also put me on birth control that same day (a positive step in the right direction moving towards IVF to regulate my cycle).  I had the saline ultrasound yesterday (March 6th), and apparently my uterus looks great.  This was relieving, yet super frustrating at the same time.  Relieving because the ultrasound came back with no abnormalities in my uterus, so I don't have to have a D&C.  Frustrating because there's no reason as to why I was bleeding so much for so long.  So let's just hope this goes unexplained and fixes itself with the birth control (so far so good - birth control seems to be doing it's job)..
Moving forward:  I have a biopsy on Tuesday March 13th.  My fertility doctor will go into the uterus and take a biopsy of the uterine lining to send out for testing (results normally take an approx. week to get back).  This will ensure whether the lining is healthy or not.  Once that is confirmed, I believe we can then move forward with IVF the next menstrual cycle, or maybe one more after the next one.  Slow start but finally getting somewhere.
