You are not leaking amniotic fluid at this point in the pregnancy - it is simply not possible! (amniotic fluid is baby's urine and baby isnt capable of making urine 1 week after conception).
You need to make an appointment with your doctor about this. It could be a number of things (burst cyst, infection etc.).
you need to go to the doctor. you may need your cervix stitched to prevent premature labour.
I'd ask your ob about it. I'm not sure what it is, unless it's just an increase in discharge, which can happen with pregnancy.
