Congrats to those hitting the v-day milestone. Pink, I hope you find out soon what's going on with your infection and the plan for treating it.
Esperanza, I though 3rd tri started at 27 weeks from reading various other posts, but my pregnancy app welcomed me to third tri yesterday when I got to 28 weeks. Either way, it's really not far off for you now. Sorry to hear you're suffering with back pain. I'm feeling surprisingly comfortable at this stage, except at night when my hips hurt if I lie on one side for too long.
