I'm carrying twins, but my twin specialist informed me that I tested positive for toxo. But stated that she wants to do amniocentesis test on me. But I'm a bit afraid of my waterbag bursting I'm 27wks. Has anyone else had this problem. The reason being for the test was because she stated that baby b head is a Lil smaller than the other baby. But, as far as ultrasounds they look perfectly healthy.
