I have three active pills left on my second pack of birth control. i have lower back pain, mood swings, basically pms.is this possible even on the pill?

Yes: Yes it's possible for you to have the symptoms even on the birth control pill. It's also possible that the symptoms will get better in a month or two. Another thing to consider is that this brand of birth-control pill might not be the best one for you. If symptoms bother you consider asking dr. For another brand of birth control pill and see if better.
