So I have had this birth control for 10 months now and not one time have I had a period. I have cramps once and a while that are so bad it feels like mild contractions following a water like liquid with no smell and the cramps only started 7 months ago. I was told it is kind of normal to not get a period when you are on this birth control.. I haven't gained or lost any weight and I have no symptoms of pregnancy and if I was pregnant I tested a month after sex and it came out negative. I'm not hoping for a child but I just think its odd I went from nonstop periods on the IUD to no periods at all with the Nexplinon.
