This is my first month on Lo Loestrin Fe. I have never taken any other type of birth control before. As instructed, I took the pill on the first day of my period and I have taken it within the same hour each day. [One time I was an hour late about it, but other than that... ] I still continue to have protected sex using another contraceptive. Today, I am experiencing spotting and painful cramps. Is this normal?

Side question: When is it okay for us to stop using another form of protection? There's a difference in opinion floating around the internet on this and I would prefer a clear answer, if possible.Thank you!
