I'm 11 weeks & 4 days in my second pregnancy.  I found out I was pregnant because I thought I had been having my period for 2 weeks. I had called my doctor because I knew my period was lasting too long. The nurse asked that I take a pregnancy test and of course, it was positive. I immediately assumed the worst and thought I was miscarrying. I had two blood tests that confirmed the baby was still okay and then I had an ultrasound at 8 weeks and saw the baby's heartbeat. I had another appt. yesterday and the doc had a hard time finding the heartbeat so he did another ultrasound and we saw our baby moving its arms and legs and a strong heartbeat but this evening I've started having some spotting. It's pink and I'm scared to death. Has anything similar happened to anyone else?
