Thanks so much for your reassurances, everyone! I had read in various places that one could expect any nausea to go away around the twelfth week, but never that ALL 'symptoms' go away. But it does sound like it's pretty normal for that to happen.
I also stopped taking the Prometrium suppositories last weekend. No more pantyliners, no more goop, no more sticking my finger up my... well, you know. It wasn't actually too bad, especially since I was only taking them at night time, but still, it's nice not to have to deal with it.
Another week and a half until my next DA. Getting to go every two weeks was so nice. I'm used to the two week wait. Four weeks seems to pass so much more slowly. Especially when nothing is happening!
