Do amphetamines cause false positive pregnancy test results?

Do amphetamines (legal and prescribed, but for that matter,any amphetamines) cause false negative hpts? Keep in mind I am not underweight or obese (thick and healthy) and I have had 1 very light, perfectly scheduled period since possible conception. My dosage of Adderall has gone up and become more consistent since then, (couldnt t always pay pharmacy bill before). I now have weight gain, nausea, and missed a period and swollen breasts all at home tests I ve taken give false. I would be 9 or so weeks at this point and I have had ZERO sexual contact since that day. That i could be pregnant is is impossible right?

Amphetamine may not cause a false positive pregnancy test.

Antipsychotic drugs, diuretics, Methadone, Chlordiazepoxide may present a false positive pregnancy test.

Autoimmune disease or rheumatological conditions present a false positive pregnancy test.

Please repeat the after 2-3 days, also get it done blood HCG levels.

Still, have queries please consult your gynecologist she will examine and treat you accordingly.

Hope I have answered your query. Let me know if I can assist you further.
