i have been on birth control since I was 12 yrs old, due to heavy bleeding. I am now 30 and have never missed a period up until this month. I have been on ortho tr cyclen lo for many years and have always had it exactly on time and stops exactly on time. very scared. took a home pregnancy test this morning and it was negative, but went to see a doctoc because I don t always trust in those things, as I have never had to do the test. they tested my urine and it came back inconclusive, they were not sure why. they then took a blood test. waiting on results.... very scared
