Miracles happen, I am pregnant!

OK, well yes according to two first response tests.  This was our first month really trying and I just can't believe it.  I already had a frozen embryo transfer scheduled for November.  We tried to get pregnant for years, then 4 IUIs and 1 IVF with my son James.  He got his wings one day before his due date for unknown reasons.  I am really scared, happy, confused.  My husband was really late last night and I just knew he had been in an accident.  I thought I was given this miracle and now I have to lose something.  He came home and was fine, just working late and no cell service.  I am going to enjoy every second I have with this baby.  I know this pregnancy can end tonight or in 36 weeks for no reason.  I really am trying to be positive but also realistic.  I pray that somehow I will get to raise this baby on earth.
