Hi my name is Jancel, I have a question that is concerning me. I had the birth control nexplanon inserted on July 21st of this year. The first few weeks was spent with light spotting periods. I currently jut got my period for this month and I noticed it was much heavier than I ve ever had. I also am having a lit of pressure in my pelvic area. It is jot cramping , and can almost be described as a feeling of rupture if I move a certain way. The pain has also moved to my lower back and is quite painful that I feel like crying. I am also receiving chills and feeling slightly light headed followed by nausea. Can you please tell me what might be causing this?
