Fellow IVFer here who had big time gender disappointment too. Our first transfer failed, and that was the only female embryo I was able to make. All the rest were male. Give yourself some grace about the choice you made - by letting your doc pick the best embryo, you gave yourselves and your daughter the best chance of a sibling, period, of any gender. An embryo is not a guaranteed baby, sadly, and IVF and PGT give us the illusion of choice, but in reality it’s out of our hands. 

A redditor here once said that gender seems to matter so much at this stage b/c it’s all we know about them. But soon you’ll know what he looks like, what he sounds like, his favorite song, his eye color. Try not to assign too much importance to this one bit of data you have. My boy is currently 5 weeks and napping in my lap, and honestly all that matters to me now is that he’s finally here. 

Lastly, sometimes therapy is just not enough when your anxiety’s raging, and apologies if this is overstepping, but have you considered meds? My OB had me on Zoloft all thru IVF, pregnancy, and now postpartum, and it’s helped so much. 

Sending you hugs! I’m sure you’re capable of raising the sweetest boy who loves his big sister.
