Have you been in contact with your midwife yet? Depending on the area you live in, a normal 1st booking in appointment with her will be between 6-10 weeks. Then your paperwork will be filled out, bloods taken and form sent to the local EPU to arrange your viability scan. The date of this scan will be aimed to be arranged at approximately 12 weeks.
I would chase it up with your doctor's surgery now as the midwife would normally want to see you by now and you may have to allow time for booking in. For example, at the surgery where I work, the midwife is booking 3 weeks ahead at the mo due to the backlash from all the Christmas & New Year bank holidays.
Good luck.
