I've been on birth control, mononessa pills, for the past three and a half years. Last night I did have unprotected sex and he ejaculated in me. He is insistent that I take Plan B this morning, but I've read that this could mess with my hormone levels and I should be clear if I take my pill regularly and at the same time every day. I'm just looking for some answers or support when it comes to not needing to take the plan B pill in addition to my birth control.
