About two weeks after a miscarriage, I started taking Ortho Tri-Cyclen Lo. I've been on it for twelve days, including today. Three days ago, pill 9 I think, I almost missed a pill, but took it later that night, around 11, before bed. (I usually take them at 7am.) Last night, my boyfriend came in me, and I'm really worried about how effective the birth control is. Please help if you can, thank you!
