My first day of last period was December 28th...I missed my period last week. I took a hpt on the 30th of January which was 2 days past my miss period. It came out positive.. I was skeptical so the next morning I took 2 more..both positive. Early this morning around 2 I experienced cramping so came to the ER. They told me my hormone levels were low and that they couldn't see any indication on my ultrasound of a pregnancy. They said I could have missed carried and not know could be a tubal pregnancy or just very early. I'm worried because I have had 2 miscarriages before and really want this pregnancy to be a healthy one. What are your thoughts??
