I'm 3 months pregnant again...

Well I went to the doctor's and I was supposed to be 15 weeks along (2 weeks ago) but I was measuring a bit small so they had me get an ultra sound. They pushed my due date back 5 weeks and now as of this week I am in fact 3 months pregnant for the 2nd time this pregnancy. My new due date is March 4th. I would have included a picture but it is a picture only a Mother loves meaning its rather blob like to the untrained eye.
