In Jan 2014 I had committed suicide with 50 tab alprax 1mg
Now I am pregnant since April 2014
I want to know is there any side effect of sleeping pills to my unborn baby or any test need to do

The medication would no longer be in your system, but the incident should be included in your medical history for your doctor or midwife to know about.

I'm assuming you meant ATTEMPTED suicide as I doubt if you would have access tot his site if you had been successful.

As noted, if you survived the attempt, your system was flushed and the toxins would be gone. So the fetus should not be affected. But your medical providers need to be aware of your history.
