Hi, I Am 21 And In Good Health. I Have

Hi, I am 21 and in good health. I have 2 year old, I am 13 days late, and feel pregnant, increase in discharge, sore breast, nausea, dizziness, very exhausted, waking up with a stopped up nose, and very very restless. I am in good health and work out regularly, one of the big things that makes me think I am is every few workouts I can't make it through my warm up without throwing up. I have never had this problem and I run to warm up. A 5k is a warm up for me have always ran. Well 3 different times in the past 2 weeks I have had to jump off treadmill half way through and can't hardly make it to the bathroom before vomiting. I take adderall 30-60mg a day. I went to dr the day before my period was due and blood test was 1.0, however the day before that I had 2 positive hpt (figured they were just false positive going off of reviews) I then bought different brands a few day later and took them and they were negative. Now that it's 2 weeks later and the symptom just get worse is it possible that the adderall is causing false negative test? I was 6-7weeks before finding out I was pregnant with my 2 year old took urine test at dr office at 4 weeks to start birth control and it was negative. So could the adderall be causing false negative? I also sometime take tramadol 50mg for my back
