"been on it for about 4 months now so maybe things haven&#039;t stabilized. i&#039;ll say that it&#039;s effective, i haven&#039;t gotten pregnant. first month was great, no side effects at all. immediately after the first month, however, i started spotting enough to need to wear a panty liner all day, and i&#039;ve been constantly spotting since. no periods, just constant spotting. it&#039;s annoying but i guess it could be worse. no other side effects that i&#039;ve noticed."
