Baseline Ultrasound

Just left the clinic for my baseline ultrasound.  Seems that pesky cyst from the last cycle has decided to stick around, except it has also decided it has wanted to grow.  So here is the deal.  Once again, we will wait for the estrogen levels to come back in the blood work.  If it is below 70, the cyst is suppressed and we will continue with the cycle as normal.  If it is above 70, I will go back tomorrow and have more blood drawn to see if the estrogen is rising or falling.  If the estrogen is rising, we will be cancelled.  If it is falling, we can continue with the cycle as planned.  The cyst was measuring about 24-30mm.  It has not completely taken over the ovary yet, but if we are cancelled out of this cycle, I will have to have surgery to have the cyst completely removed; since it is hindering our ability to harvest eggs.  If we are able to continue with the cycle and are able to actually harvest eggs, the cyst will be drained at the time of harvest.
So I am experiencing something new with this cycle that I have never experienced.  I am having a full on period while on the BCPs.  It really concerned me.  I started having all my normal pre period symptoms last week; scours, pain in the right side (the side with the cyst), bloating, spotting, and just feeling like I was going to start my period any day.  Of course iPeriod said I was due to start on Sunday night.  I emailed the clinic on Friday to let them know what was happening, and should I be concerned.  Well, sure enough on Sat (Feb 10th) I started my full on period.  I texted my RE (we are friends as well), and she alleviated my fears.  My concern was that how is the BCP going to keep me from ovulating if it can't even keep me from starting my period?  In all my cycles with the clinic in all these years, I have NEVER had a period on BCPs.  She stated at this dose, they are only concerned with suppressing the ovaries and they don't really care what the lining of the uterus is doing because we are doing an FET anyway and to not worry about it.  I said ok and we went about our weekend.  I get a response back from the MA on Monday and she says that it is normal to have breakthrough bleeding on BCPs.  I had to inform her that this is NOT breakthrough bleeding, this is full on period.  So when I went into the clinic and saw the RE today, she laughed and said welcome to old age and the club of how BCPs don't control your periods anymore honey!  I said that's not funny!! I thought something was wrong!  She laughed at me some more.....
One thing that is also different about this cycle and these BCPs, I has a pre period migraine.  I haven't had one of those since I started back on my Trokendi XR at the full dose of 200mg.  So something about the extra dose of hormones over throws the migraine drugs.  Miserable.  That's what it is.
So here's what's now going to happen.  We wait.  We wait for the estrogen levels to come back.  If we get canceled out of this cycle because of this stupid cyst, I have to have surgery to have it removed.  I have to schedule that surgery as quickly as possible 1: because my AMH can't take much more of a hit, and 2: because this cyst can't get much larger.  If it does it will over take the ovary and removing it will destroy the ovary.  No, we can not just drain the cyst, it has to be removed.  Draining the cyst will only allow it to come back.  Since it is still relatively small, it can be removed safely, without destroying the ovary.  So here's hoping it is suppressed and we can continue.  Fingers crossed.
