"i started taking ortho cyclen on april 17, 2016. for the first month, i had no side effects, but after my period ended, and i started a new pack, i immediately started throwing up about 12 hours after i took the pill.  i was extremely worried, so i took pregnancy tests, but they were all negative. i ended up receiving my period in may, which meant that i wasn&#039;t pregnant! after my period again, i started throwing up again, still about 12-13 hours later, but it only happened for about 3-4 days. i guess, my body just isn&#039;t used to all of the hormones since i&#039;ve never been on birth control before. i just had my june period, and i threw up for one day, but other than that, everything is great! i&#039;ve had some weight gain, too."
