An unsigned check and an unanswered email

Surrogacy comes with several costs

• Pride
• Modesty
• Hope
• Time
• Dreams
• Money

As a surrogate the first time I had no representation/ no protection from myself and my giving.  I did not remember what a pregnancy would cost.  I did not understand the cost of driving, food, cravings, change in "must haves", clothing for work and home.  The second journey I had an agency that believed in reimbursement instead of monthly allowance, I would rather have a monthly allowance.  So I collected receipts and submitted for reimbursement.  Some of the items allowed for reimbursement are:

• Mileage
• Parking
• Meds
• Vitamins
• Lost wages
• Meals when traveling
• Airfare
• Taxi Fare

My negative BETA was November 16, 2011 (sad heart), cycle started Sunday November 20,2011(Feeling Icky), Thanksgiving November 24, 2011, guests arrived that Tuesday November  22, 20110, IP's ended contract (that was their last embryo), my daughter passed out and fell, (face first), down the stairs(after getting the Turkey in the oven), our guests left Saturday November 26, 2011 and my husbands parents arrived Thursday December 1, 2011.  All this while working full-time.
December 7, 2011 I got an email from the agency to get my receipts in.  Got them in two days later, but found out the escrow account had already been closed by the parents, before I was asked to get in my receipts. I was told I would get the money, the agency offered to contact the Intended Parents.  This isn't a lot of money comparatively to how much a pregnancy would cost, they had already paid flight, hotel and rental car, but still a $$$ amount.
I did get the $$$, I received a kind Christmas card and an "unsigned" check.  I wrote an email after praying hard on how to approach the subject.  I had already failed at getting pregnant. I had submitted my expenses after the escrow was closed.  I have not heard back from the IP's. An "unanswered" email.  
I do not know what to do.  I am letting it go.  There is no one to blame.  I trust these IP's.  I just feel as though I need to be honest with my journeys.  This stuff happens.
In the area of Surrogacy we are dealing with human beings.  Emotional, Living ,Breathing, Dreaming, Flawed, Perfect, Hurting, Giving, Desperate, Grieving, Empty, Questioning
This is a journey I want to be on.
