Nexplanon?

Is it true that women under 150 lbs have the most problems with the nexplanon? (As in, spotting, bleeding for months, moodiness, etc.) I really want to get the implant but I’m 100 lbs, very petite, and I’m scared I’ll have horrible side effects. If you’re on the smaller size and have had the nexplanon how did it go for you? What did you experience? And would you recommend it?
