Hi. I was told that I am six weeks pregnant so I went to the ER bc I was and still at times am having spotting with mild to no cramping. The ER doctor said that my hcg levels were at a 600 and that was low for me to be six weeks. I am overweight so I am very concerned and they also said they were unable to see anything in my uterus should I be concerned about this??? Plz this is my first pregnancy and I am scared.
