Hi I'm 25 and don't think I can get pregnant because of my irregular period. I only get my period if I'm on birth control. If I stop then I will NOT get it. I went almost a test without taking it and didn't get my period once doing that time. I recently started taking it again because we plan to have children. I'm guessing it my estrogen level. I'm only 25 and I'm experiencing vaginal dryness. Which makes me not enjoy sex. Please help.
