I currently have the nexplanon bar but my fiance seems to think I am possibly pregnant. Over the last month I have had weight gain, my boobs have gotten noticeably bigger & hurt, I've had more acne than usual, been tired, sore & moodier than usual. All these changes have been noted by him (I only noticed my boobs had grown after I got new bras & they hardly fit after a week) & he seems convinced I could be pregnant, I just don't think I am though.
