27 weeks Pregnant on Opiates

Well I’ve been taking painkillers for two yrs now and haven’t stopped since I become pregnant I slowed down the dosage a lot though only taking one pill a day . And starting to split the pill in half . Doesn’t matter the mg I split them it can be 5’s ,7’5s or 10’s I’m taking lortab btw I’m trying to quit . It’s hard I’m just concerned that my son is addicted to them also . If I stop now will he be ok I’ve been goin to all my doctor visits. He’s been doing perfectly fine growing well no problems .. any advice or input .
