And I kept a heat pack on my lower abdomen.. To me the heat pack was a life saver.. I went to bed, woke up 45 minutes later had lots of blood so went and had a shower.. I felt a huge clump come out and looked at the ground and saw the embryo sac (I was 6 weeks and 4 days) I could see it all quite clearly and had to call my friend to come help me as I was in shock at what I just saw..
all in all I would say other than seeing the sac I had a good experience and pain was minimal.. Please don't be scared of this.
