My boyfriend and I had unprotected sex earlier today and I'm worried about getting pregnant being that I am not yet on birth control. My doctor prescribed me Gildess 1mg-20mcg and I'm supposed to start it in two days (on Sunday), however in my current predicament should I take plan b and start my birth control tomorrow? Should I only take plan b and then wait a month (until my next cycle) to start my birth control? What should I do?
