Hi Lisa!
I responded to you over in bearing w/ bedrest, but thought I'd respond here, too. I do have a bicornuate uterus and have given birth to three sons.
I'm not currently pregnant, but wanted you to know you're not alone! (Doesn't it kind of feel like you are when you hear this kind of thing? I felt like a freak of nature when I found out about my uterus, ugh.)
Overall, my pregnancies were good ~ besides early Braxton Hicks contractions and the baby running out of room to move at the end, and delivering by C-section. (With my last baby, I had placenta previa, but that was more due to the fact that he was section #3 than to the fact that my uterus was bicornuate, I believe.) It's all worth it when you're holding your precious baby. My best advice to you is to take it easy from day one. Drink lots of water, and put your feet up and rest as much as you can. If your dh is able, have him start to do the grocery shopping for or with you. And my biggest advice is to listen to your body. No dr., mother, sister, friend, etc., knows exactly how you're feeling. They mean well with their advice, but you know yourself the best. Start trusting your motherly instincts right now, because you'll need them more than ever in the 18 years to come :)
Congratulations on your pregnancy, Lisa!
If you have any questions, please pm me. I check those a few times a week. I'm usually not even on pw, but I've felt a need to come and check out the boards lately. ;)
You and your little one will remain in my prayers.
