I skipped my period last month with the pill by skipping the inactive pills. About a week into my new pack or so i started spotting. I had had unprotected sex and thought i might be pregnant, but the bleeding kept getting heavier and when i had 3 active pills left before my period, i started my heavy period flow. I was also taking an antibiotic when the spotting first started happening. I am supposed to be on my period this week but im not because i had it for 5 days last week, is this normal? i took an early pregnancy test 3 days ago and it was negative, so could it just have been because i skipped my last period and because i was on antibiotics?
