The birth control pack I take says lomedia 24 fe, but my doctor calls it loestrin or something like that. Anyway, I used to take tri sprintec but I switched and this is the first month I've taken the new one. I'm on day 3 out of 4 of the brown pills and no period. I haven't skipped any of the pills either. I've had some symptoms of my period though, just no blood.
