I have been taking Phentermine 37.5 for 5-6 weeks. My last menstrual cycle was the week of 11/13 (usually a 8-10 days Med-heavy flow) my last prescription was written on 11/29, I took a home pregnancy test the day before or after my 11/29 prescription (honestly can t remember, just know I took it to make 100%sure) it was clearly negative. I have taken it everyday, never skipped a dose. Today I took 3 different home pregnancy tests that all showed positive or light sign positive. No signs or symptoms of pregnancy (I have 3 children so I know them all )& I from what I can gather I d either be a day or 2 late or I m a week off via my last period date. Like it was the following week or I started right in the middle of said week. Can I get a false positive from the Phentermine?
