Been on Nexplanon for 2 and a half years now, going on third, 2 more months until the 3 year is supposed to end, towards the beginning of the time I got it put in I was feeling nauseous, continuos periods for months straight eventually the periods stopped for a good 6 months and then returned the last few months I ve noticed I ve gained lots of weight but not feeling any pregnancy symptoms could this mean I m just gaining weight and not be pregnant or could it be a possibility that I am pregnant If I ve had intercourse within the last 2 months of the time I need to get it out for a new one. Need answers please asap
