I do the same thing, thinking about jinxing things. : ) I think being worried is completely common and normal.
I feel AWFUL today. My allergies are still driving me crazy, and the vomiting level of MS hit me this morning. I'm a teacher, and today we had a field trip to go hiking on a nearby mountain. I am completely exhausted. I was supposed to go pick up DS and go to DHs ballgame, but I am so wiped out that I begged my MIL to keep my son late and let DH pick him up after he finishes coaching. I just walked in the door, and the plan is a bath and a nap!
I feel miserable, but I just keep telling myself that the nausea can be a good sign that all is well. : ) I hope you ladies are all feeling well!
