Can The Use Of Methamphetamines Mess Up A Pregnancy Test

Can the use of methamphetamines mess up a pregnancy test result? I've had a lot of strange butterfly feeling in my stomach for a few weeks, and I waslaying with hand on my abdomen and I swear I felt something move and it feels exactly the same as my first pregnancy. I took four tests once all negative but felt something kick my hand so I went to doctor and found out I was 20 weeks 6 days pregnant. I've taken tests with amphetamines in my system and they have been negative.
