First I want to say Congrats to all on your new bundles of joy. I lurked here for about a week before posting, I have a serious matter that I need help with. I found out Im expecting on 9/14/12 at 4 weeks, I am now 5 weeks and recently started spotting and I freaked out because I miscarried about 4 months ago. I went to the ER and they checked me and said my hcg levels were ok but the ultrasound didnt show anything should I be worried? I am so scared all I can think about is not again, I have a doctors appointment tomorrow to check my levels again hopefully everything is ok and my lil bean sprout is thriving.
