"i will start by saying that while on the patch for about 6 months i felt fine... no bad side effects. i follow directions religiously for this stuff because becoming pregnant was not something i had planned. however, after 6 months on the patch and using condoms, i found out i&#039;m pregnant. 16 weeks pregnant to be exact. because xulane did make my periods irregular, i had no idea i was pregnant until 14 weeks. just a heads up to the girls wearing it. it didn&#039;t do much for protecting me from pregnancy."
