Yay, that’s fantastic! I am following along with your saga, as I am early in my pregnancy and rooting for happy healthy pregnancies for all of us who have struggled to get pregnant, including random blogs I encounter on the Internets. We did IVF (well technically it was FET since we used frozen embies).
I have a daughter from our first try of IVF and went into preterm labor at 33 weeks (much less scary than anything in the 20-week range, of course). I just wanted to share with you that I tested POSITIVE in the fetal fibronectin test and did not deliver until 39 weeks. So, even if it does come out positive at some point, Olivia Moonpie may still stay put awhile!
