Have you had a vaginal ultrasound done? Early in my pregnancy I experienced what I believed was a miscarriage. I had all the classic symptoms. My OB/GYN MD drew an HCG level (pregnancy test) to see if a D&C was needed. He called me back to his office that same day stating my test was HCG level was very high. I had a vaginal ultrasound in his office and that is when it was discovered that I had either miscarried 1 fetus or I had an implantation bleed. I was still pregnant with twins and to his amazement he discovered that I had a bicornuate uterus (a heart shaped uterus with a septum dividing it into 2 parts- the twins were on one side). He was amazed that I became pregnant and with twins, possibly triplets to start with. To make a long story short I delivered 2 healthy twin girls at 36 weeks- weighing 4 lbs 12 oz each. We all went home 3 days after having a c-section over 5 years ago. I have 2 very healthy (and a bit spoiled) twin girls.
