Does taking contraceptive pill lead to false negative drug test result?

Hello, I need to take the morning after pill tonight. How can I be 100% sure it won’t throw off a drug screen? I’m just worried an ingredient will show up and look like I failed a urinalysis. The drug screen has to be taken tomorrow or the next day. Thanks, A

Hello dear, welcome to HCM. I read your query and understand your concern. I think taking the contraceptive pill does not interact with other substances in urine analysis. Hope it was helpful, if yes vote helpful.

Hey, I needed contraception and have tried about 4 different pills throughout the course of my relationship (currently a year and a half) all with negative side affects. I had to cease taking them for my own well being and when seeking a new method of contraception despite wanting to avoid hormones my doctor convinced me to try Implanon. I had it in for 3 weeks before my mood deteriorated to the point where I no longer wanted to live. I had it out a week a go and still feel incredibly emotionally unstable. I was just wondering how long will it be until my mood returns to normal?

have been on birth control for about half a year and I have taken basically perfectly, and this month I took every pill on the dot. Well eleven days ago I had sex without a condom and a few days later I felt a little sick, but a bug was going around. I took a pregnancy test yesterday (10 days after sex) and it was negative. I know that was early now and could be a false negative. I usually get my period on the 3rd placebo pill and today I just took the last active pill this morning and tonight I started spotting brown here and there. I am wondering if I am pregnant or if this is the start of my period, just earlier than usual by 3 days (it does usually start out brown). Am I pregnant? Also, when can I take another pregnancy test?
