Aw congrats! I found out I was preggo 11 weeks ago (I'm now 15 weeks) and cried and cried. I thought this year would be the year to get my body back. Week 7-12 was really rough for me. I just had to rest a lot. After that things have gotten a lot better and dare I say I feel better than I have in awhile. I chalk that up to rising progesterone. I also take suppositories of progesterone through week 15 because I've had losses in the past due to low levels. SO yeah...Just make sure to rest and eat well :)
Like Saljoe, I was oober frightened about the delivery but really when I think about it, there's so much more joy than there is the trauma of even a hard birth. Breastfeeding especially gives us those great hormones that make us feel great! It's awesome you're going with a midwife. I love mine.
