Crazy Clomid, Can't We Be Friends?

To recap:

1990-2000 doctors dismiss my concerns about irregular cycles, painful cysts, horrible acne, hairiness, underweight (98lbs), infertility, etc.

got pregnant in 2001 (weighed 100lbs)
miscarried in 2nd trimester due to Triploidy XXY (horrible experience with military hospital staff)
took Clomid in 2002 (military doctor had me taking it while my husband was deployed WTF?)
husband home, took Clomid again ... nothing happened
next month, pregnant! (weighed 105 to 110lbs)
had gestational diabetes
2003 gave birth via c-section to almost full term & mostly healthy beautiful baby girl
2004 TTC
2005 TTC
2006 TTC
2007 - diagnosed with PCOS, told by OBGYN fertility would miraculously come if I would loose weight - I weighed 136lbs then (in 2007) and I'm now 125lbs (in 2008) and still not breeding
2003-2008 didn't utilize BC, that's FIVE YEARS

Currently: 2008
April began Provera
May 5mg Clomid cd 5-9
June 5mg Clomid cd 5-9
July progesterone tested on cd21 "32.40" whoopee may be pregnant
July HPT on cd31, BFN
July cd32/cd1, visit from AF, miscarriage? normal period?
July cd2 doc says normal period, feel let down, frustrated, sad
July cd3 have intense headache, am irritable, cramping like a MoFo

thinking about skipping clomid this cycle
have to decide before saturday
wondering if i'm tempting fate, was after all, already given one healthy baby
is two too much to ask
it's not like i'm getting any younger
the risk just keep adding on from here on out
but hey, it appears that i actually ovulated last time
that's good news
right?
so why didn't i get pregnant
rabbits are jealous i tell you
so clomid, let's me and you be friends already


*EDITED To ADD:
The Husband went out of town for work, so skipped some cycles, then
November 10mg Clomid cd 5-9
December 10mg Clomid cd 5-9
The Husband back out of town for work, so skip half a year of cycles for 2009
