So im on microgestin fe 1/20 and i was told that less than 1 in 100 women get pregnant a year. Well i was telling someone thats why im on birth c was because i wanted to be protected abd not have children anytime soon. Well she then continued on about how birth c isnt effective because she was on birth c and condoms and spermacide abd she still got pregnant and that using just birth c alone wont work. I have never missed a pill and im not on antibiotics. As well that the 1 percent of women who do get pregnant typically forgot to take the pill or again they were on a medicine that counteracted the birth c. Should i be worried and use back up protection or was what she said just misinformation
