Hi, Last Night I Was Having Intercourse. I Recently Got

Hi, last night i was having intercourse. I recently got married and lost my virginity 2 weeks ago, i bled the first times, and off and on during intercourse, not everytime but occasionally. Anyways, last night during intercourse i bled a lot, and afterwards I felt nauseous and weak and almost vomitted. Is this ok? Also, I am on birth control and 3-4 days before my period should start. Also last month I skipped my period using my birth control pills.
