I am taking Trilafon and I know it can produce side effects of pregnancy. I have been bleeding every month for the past three months-on time. If I were to calculate the dates I would be 19 weeks. I have lost 3 pounds, but my belly and chest are getting bigger. I saw my fiancee recently and he brought up the fact that I might be pregnant because of the changes in my body. Does anybody know anything about hysterical pregnancies? Could I be having one?
