Living in a body I don't even know anymore...

My m/c lasted about two full weeks and I had "higher than 5" hcg draws for 2+ weeks afterwards.  I was told it could be 5-8 weeks before the next sign of any blood.  So imagine my surprise when 4 weeks post-m/c I start bleeding profusely over the weekend.  It was way more blood than I would have thought possible after the m/c and considering it had only been a couple of weeks that it could have been building up.
My old cycles were always 35-40 days long so that threw me off too.  Now I don't know if I should expect "normal" cycles of 28-ish days since that's what this seemingly was?  Or if I'll go back to the extra long ones again? With the chances of us getting pregnant on our own really slim, I don't know if it's even worth attempting to figure out when I'm ovulating.  I am definitely living in a body I know nothing about anymore.  It's very frustrating and when I try to talk to DH, his answer is, why are you worried about it?  Umm, because I don't want to carry an arsenal of tampons and the like wherever I go not knowing when the floodgates will open? 
The weirdest part is that I always have really bad headaches, cramps and bloating a few days pre-period.  DH would say that I am really moody as well.  He would be correct.  So there  has always been an indicator in the past.  But this time, besides the tremendous amount of blood, there was nothing.  It's baffling really.
In the meantime, I had my 6 week post-m/c draw to test for Factor V, MTHFR, etc. etc. etc. to see if they can determine why I lost the kids.  Oddly enough, DH's family has tested positive for the clotting disorders.  DH is a carrier of MTHFR but not Factor V.  Since this lab work is pretty extensive (it better be, nine tubes of blood later!), I couldn't schedule my follow up with the RE until Sept. 21.  So again I'm waiting, waiting, waiting.  My dad suprised me with flying me to Florida for my stepmom's birthday so I'm looking forward to that from the 30th to October 5th.  That at least keeps my mind off things somewhat.
Finally, a crazy "I couldn't make this up if I tried" moment--during my big draw last week, the tech at the desk at the satellite lab I go to comes into the room and says to the phlebotomist, "I can't find what this one code is.  I googled it, and it says Factor V Leiden, so I assume that's what it is."  The phlebotomist agrees that's probably what it was, especially if typing that code into Google yielded that result.  I am sure they are right, but the fact that they were googling lab codes as they drained me of nine tubes of blood made me laugh at the sheer ridiculousness of it all.
At least I can laugh!  God is great.  I continue to enjoy life in the meantime and I hope my next appointment has a positive outcome with no googling necessary.
