I stopped seasonique 6 months ago had 3 reg periods, late last month by 5 days and light. Now im 9 days late. I was never late before seasonique and now I don't know if this happens after u stop birth control pills or if I'm pregnant? I had 3 reg periods that are 30 day cylces. I also took a test after being late 5 days. And it was neg. So when should I take another?
