I need help! We've been moving recently, and I haven't been doing any work that I know will effect me. I've carried a couple of bags, and a couple of lightish boxes. And tonight when I went pee, I felt a lot of pressure down there, and I'm still feeling it now that I've laid down. I'm in my third trimester with twins. Is this a problem? I googled it which was a mistake because it all scared me.
