I had my 20 week ultrasound today, and baby #5 looks great. I unfortunately have a low-lying placenta, but after talking to a few other women about it, I'm early enough it should move up and not cause us any problems. There is no guarantee it will move, but it generally does, so I'm hoping things work out. I go back in 6 weeks for another ultrasound to see if it has moved up.
Later I will scan the one really good picture we got today, but for now enjoy the picture of my ever growing belly (and butt apparently as my butt grew a ton).
and for comparison this was my 16 week picture:
