Hun, one of my baby buddies is pg with a baby conceived through IVF while she continued BF her DS - so you don't necessarily need to wean. she had to have two stim cycles to get a healthy embryo and is now about 6, maybe more, weeks pregnant and continues to BF her one year old.

as to the results - i really have no idea, but i'm wondering if the fact your cycle hasn't returned is impacting you at all. hope you can get some answers next week hun
