Could I be..?

Makyla

I switched birth control from nuvaring to the pill, and I'm on my 3rd week. My doctor said I *should* be safe having unprotected sex so I have been with my boyfriend, but I have forgotten a few pills until late at night because of work, and I had odd discharge and sort of pink this morning.. I start the sugar pills on Sunday, but I'm still worried. Am I safe or..?
