Can't vent anywhere else but here.....

Here's my story my husband and I started to try for a family in 2009.... we were married in 2007 and wanted to wait. After a full year of trying with no success we decided to get help. After many tests and ultrasounds it was determined I have troubles with ovulation and a heart shaped uterus. After 2 cyles of clomid we were successful and had our son in March 2011, then by some miracle we got pregnant without trying and had our daughter in July 2012(15 months later). Fast forward to 2014. He and I have decided to try for our 3rd and last. With no luck.... I turns out I have to start my cycle of clomid once again.... and I am not able to tell anyone but him bc we don't want the family to know we have decided to try for a 3rd since they stressed me out and became much to "HELPFUL" when we tried for our son. Plus we don't want to hear the "you have 2 healthy kids why bother" statements... I tried to talk to my husband about my irritation to be right back to this plus the increased chances of having multiples..... but he doesn't seem to understand where I am coming from. He makes little jokes and about having to use the clomid and how I am "broke" but I can be "fixed".... I feel it is his way of venting his fustrations.... anyone else been in this situation? Any advice? We have accepted and understand the risks of having multiples but we both feel comfortable with the chances of having 4 Kiddos instead of 3.
