The answer is yes. Since you are on the pill I would also suggest taking B6 since it is depleted by birth control pills. Don't go overboard though since high levels of one B vitamin can push other B vitamins out of the body. A B50 complex daily should be sufficient with a good diet. Your doctor can have a lab test done.
Symptoms can sometimes be a giveaway as well, such as excessive facial hair in women.
The birth control pills would make me suspect, at least in part, a B6 deficiency. You may want to try oatstraw or rice bran which are both good B vitamin sources and silica sources which are both excellent for the nervous system.
