Ditto! I'll be 29 weeks on Saturday and geez...I'm so tired! People are starting to ask me if the baby is coming soon and I'm like "Nope, three more months!" Ugh, 3??? Really??? I guess it's more like two and a half now, but still.
Try to enjoy these last 3 months. You will feel like they suck balls and wish they were over, and once it is over you will have that precious little prize at the end, one day though you may want to do it all over again. You will forget about the morning sickness, the back pain, and feeling like you are sitting on a softball (and labor). It's the way we're wired.
I can't have any more and don't want any more, but I do miss the pregnancies and breastfeeding the most.
