"i was on balziva for the past year but my new insurance won&#039;t cover it so my doctor prescribed blisovi. i am on the first week of my second pack. i got my period with heavy bleeding on the second week of my first pack then continued to have cramps until the fourth week. i had spotting when i was supposed to have my period according to the pack. at the beginning of each pack so far i&#039;ve experienced horrible nausea. i thought it was my body adjusting to new medication but after reading these reviews i may need to take these symptoms up with my doctor."
