Day 10 and Day 11 after embryo transfer

Day 10.  I did a pregnancy test and i used a different one and it came up negative.  but then at night i used the normal one and it showed a positive.   .  its doing my head in .... all this testing is not good.   showed hubby the test but he reckons he couldnt see two lines...  I was going a bit crazy..
Day 11.   I did test and it was positive.  I drove it around to a friends house and she could see 2 lines..  ha.  hope this friday its definately a positve when the nurse calls.  I came home from work and collapsed on the couch.  I didnt make any dinner and slept for about 1 hour.   My poor son was calling me but i couldnt get up...   so tired today..  my stomach is very bloated.  i actually look pregnant.
