You should really try and hold out until you get some answers. I know the waiting is torture, but it will be easier in the end if you have some answers. I'm stuck in the waiting world for our IVF. I don't start until my next AF and I've got about 3 weeks for that. Part of me wants to say F*** it and try this month, but if I have to go through another loss, I might just crawl into a ball in the corner and stay there. But at the same time I would like to have a baby with out any MA. We just can't do it though. Another loss would just kill me.
Anyway, it's just my opinion about you waiting. In the long run, it is your decision and we're here to support you the whole way. Best of luck in whatever decision you make.
