i have been on triphasil for about 5months now. I havn't missed a pill since i started using it. my problem is i had unprotected sex about 2 weeks ago, a day after my cycle and was taking my pill daily... but i am now experiencing nausea from time to time and feeling faint and tested my urine and detected protein. Could i b pregnant? Should i discontinue using the pill? HELP. Portia
