Tomorrow my baby turns 1. I had 2 very heavy post party's periods and then found out I was pregnant in December. According to my last period I am 17 weeks pregnant. At my appointment yesterday my midwife said I was measuring nearly 20 weeks. She wants to wait until my ultrasound in a few weeks to make any changes to my due date if she thinks they should. Wondering anyone has had this experience and ended up having their date changed??
