a drug profile is almost always tested in a prenatal panel. best thing to do is to come clean to your doc and make sure you aren't putting the process of becoming pregnant at risk. of course if you become pregnant and there is heroin in your system that can still cause damage to the fetus. plus the dr. can alert child services if you are pregnant with a positive drug test.
will heroin show up during fertility blood work? i'm having cycle day 3 blood work prenatial pannel and genetics. i don't usually do drugs and of course i did right before my period and now i have to get bloodwork done. will my doctor be able to tell? will they test for drugs?
