yes i would say this is normal. i never really got sick but i did feel a little nauseated at times, but of course, i think its from the extra hormones as well. and i probably did it a couple months then i was fine. my periods are normally a lot lighter everytime since i've been on the patch, so i enjoy that, and you'll find that you'll start and stop about the same time every month, so it's great to know when exactly you're supposed to expect it, especially if you're sexually active! if you have any more questions just hollar!
