I am so glad to hear that everything is OK! Bed rest is tough, but you and your baby will get through it.
When I was pregnant with my first son, I had a similar experience. After a really bad scare, and a few days on bed-rest, the Dr.s attributed the pain and cramping - without bleeding - to my pelvis, hips, and abdomen, all suddenly expanding. The rest of the pregnancy went fine, and that was the only complication.
Either way, it will be good for you to pull back from work as much as you can, and take care of yourself. I hope that this is the last scare, and that the rest of your pregnancy is great!
Please keep us posted!
