The question is 'why' you want it done ?
If you are pregnant - congratulations - I recently checked the research for a friend, and up to 30% of pregnancies miscarry. But less than half of the time the woman knew she was pregnant before she miscarried...
I hope your pregnancy 'sticks' if that is what you are hoping for...
My GP in Sydney 'confirmed' my pregnancy using the 'did you do a home pregnancy test ?' Yes 'was it positive' ? Yes - Congratulations! method
