Sounds like ur in good hands! Don't waste ur time thinking why me, or why do u have to do IVF, the answer doesn't exist lol, it's just something u have to deal with, not dwell over. I'm happy to hear ur doing everything possible, I reckon DH is right and u'll be preggers soon. Don't freak out abt not being able to cope with IVF, it can be an emotional roller coaster (as is ttc) but it's relatively simple compared to all the stuff that comes with being pregnant!! (in my experience).
Def try the Chinese herbs in the meantime and maybe ask for thyroid and immunity testing prior IVF. All the best!
