I started taking Lo Loestrin Fe this week, of course I was stupid enough to not read my pamphlet. I had unprotected sex after taking two of my birth control pills, my boyfriend did not ejaculate in me. I didn't want to take any chances so I took a plan b pill the very next morning. I've been taking my birth control at the same time ever since the incident. Am I at any risk of being pregnant? Or is my birth control not going to work anymore?
