New to fertility process, appreciate guidance/love!

Hello new friends! Myself (30NB, AFAB) and my spouse (30NB, AFAB) have just started the process of creating life with my flesh (my spouse does not want to carry and I do). We have our first appointment with a fertility clinic to discuss proceeding with IUI with donor sperm tomorrow and I’m overthinking/spiraling about options, specifically IUI vs IVF.

I’ve always said that IVF wouldn’t be for me and if I couldn’t get pregnant without it I personally would consider that a sign from the universe that I should adopt instead (to be super clear these are my own beliefs about my own relationship with the universe, not what anyone else should do; IVF is a fantastic option and I’m glad it’s available to families!) but now that I’ve thought about the possibility of getting pregnant I am reconsidering my stance because the idea of not being able to makes me sad.

Complicating factors: I’m fat and not sure if IVF would be an option anyways.

I guess what I would really love to hear is experiences from other fat folks, reassurance that IUI first isn’t unreasonable, maybe some success stories, and thoughts/advice on which way to go.

Thank you!
