Hi Emma, I can totally understand your dilimma atm and its so hard to decide isn't it? I guess ultimately its what you feel comfortable with...just one thing I want to point it out although I am no way expert on this, I think there is still risk of ectopic when doing IVF. I asked my FS about this sometime ago and thought its completelysafe with IVF, suppose they'd put it in the right place right, but they explain that embyo can move around after TF and it is still a risk IVF carries but I guess would be a lot lower than natural but I am not sure. Hope others might be able to give you a clear answer. Good luck hun on whatever you decide...
