"i got mine implanted in december 2008 and for the most part, it was great. the irregular periods are really annoying and i&#039;ve had a slight weight gain since then, but none of this was bad enough to make me complain. and actually i was singing implanon&#039;s praises until this year. the mood swings i have now are ridiculous. i am the meanest, most vicious version of myself. it&#039;s a constant struggle with myself, trying to figure out why i am so angry all the time, and why over something so stupid or small. i am the absolute worst the day before my period starts, and i&#039;ll have no idea why. then the next day i&#039;ll get my period, and i am fine, and my mood just deteriorates daily from there, until my next period."
