I am on my first month of lo loestrin fe and will be taking my second brown pill today. I had slim to almost no cramps. Is it normal that i have not yet had a period?? My doctor told me to give it about 4 months for my body to get use to the BC since I was previously taking Ortho Tri Cylen and this BC makes me feel completely different. Is this normal to not have a period or even cramps?
