I am wondering how often should I get ultrasound after 28 weeks in order to monitor my baby's development. I have APS and I a on heparin inj. Also, had a cervical stitch due to incompetent cervix. Last week, had liver function test done and found that I have slightly increased sgpt ans doctor has given me udiliv 300 twice a day.. I read somewhere that at we 28 weeks, one should do weekly ultrasound in case of high risk pregnancy. Please advice.
