All looks okay. I officially love my OB's office. I was expecting to get a call saying, basically, spotting is normal and call us if anything interesting happens. But they called me right back and asked if I could come in, immediately. (Maybe it was because I kept saying, "Spotting. AND CRAMPING.") I grabbed my bag and ran out of the office without even telling anyone I was leaving. I am SO GLAD my OB is a block away from my office. I got there in about .675 seconds...then waited for 45 minutes for an ultrasound room to open up. I almost had a nervous breakdown in the waiting room. My OB's partner, who will henceforth be known as Dr. Awesome, did a pelvic exam ("looks like some brown discharge here"--uh, yeah, thanks) and then an ultrasound. She saw the heartbeat and said it looked good; I, as usual, couldn't really make it out (except for a brief flicker), but the kid seemed to be pointing its head at us so we couldn't get a really clear side view. Dr. Awesome also had me have blood drawn to check my progesterone levels, just in case. I'm to take it easy--no vigorous exercise or sex--not that I was doing any of that anyway.
Phew. And my new mantra, thanks to Pru, is NBHH.
