"i got the nexplanon about 6 months ago. my doctor warned me about irregular periods  but i didn&#039;t think it would be a big deal. my insertion went well, i had minimal pain and only a little mark. my side effects were a little weird at first but normalized. everything was great first couple months. what i don&#039;t like is my weight gain, and my period was just too irregular. i feel like i have always had a healthy menstrual and the flow is completely off, sometimes it&#039;s 4 days  and right now it&#039;s been 2 weeks and is getting heavier. i&#039;m hoping to have it removed within a couple of months and try something that will give me consistency."
