I think I'm going to throw up

My period is a week late. Now, this is nothing unusual for ME. But I was also feeling more tired than normal and a little bit weepy and a bit nauseated. I took a test this morning and I am pregnant. I am also a little scared. With my history and all, it's a bit nerve racking. Now I have to find a new ob. Oh Lord. According to the web sites I am 5 weeks. That is still 4 weeks before I had my u/s with Riley to know that everything was ok. I hope that the new ob is willing to order an early u/s for me. I can guarantee that I will need it. Just for my own peace of mind I will need it. On the plus side, I am not avoiding meat yet!
