HELLO I RECENTLY FOUND OUT I WAS PREGNANT THE PROBLEM

HELLO i RECENTLY FOUND OUT I WAS PREGNANT THE PROBLEM IS I HAVE BEEN SNORTING OXYCODONE 30 MG PILLS FOR A WHILE NOW NOT EVERY DAY BUT FREQUENTLY AND I AM TRYING TO STOP SO I HAVE BEEN TAKING A SMALL PIECE OF SUBUTEX DAILY TO HELP. I AM ABOUT 8 WEEKS ALONG MY MAIN QUESTION IS COULD I HAVE ALREADY DONE DAMAGE TO THE BABY AND IS IT SAFE TO STOP I HAVE READ SOME THINGS THAT SAY I SHOULDNT JUST STOP BECAUSE IT COULD BE DANGEROUS TOO.
