Withdrawal can last anywhere from one week to a month. Length of withdrawal and severity of symptoms will depend on amount used, length of use, age and other factors. Synthetic opiate withdrawal from oxycodone, suboxone or methadone can be just as difficult, if not more difficult than heroin. Symptoms will include severe muscle aches and pains, diarrhea, sweating. Many will experience loss of appetite and inability to sleep.
How Often the Test Is Done During Your Pregnancy. Women might start getting weekly or twice weekly get a nonstress testing after 28 weeks if you have a high risk pregnancy. (Before 28 weeks, the test isn't accurate.) Some may only need one isolated NST if the baby is not moving well. You may need the test more often depending on your situation. Ask your doctor.
The premise of the NST is that a well-oxygenated, non-acidemic fetus will spontaneously have temporary increases in the fetal heart rate (FHR). Vibroacoustic stimulation can wake the fetus, and is sometimes used to speed up the test or to facilitate further evaluation of a nonreactive nonstress test.
