I have had the rod (nexplanon I think its called?) for nearly 2 years. I have a 2 year old and got it inserted when he was about 3 months old. I've never had any major side effects from it before, just an irregular period. Some months I get a period and some months I don't and the volume of bleeding varies. This past week I've not been as hungry and had waves of nausea. I've also got sensitive breasts (which never happens, only early in my previous pregnancy) and I've felt exhausted but I have had a hectic week at work so it could be this making me tired. I know i should take a pregnancy test to make sure but from doing some research online, less that 1 in 100 women fall pregnant while on this contraception so the chances are very slim. I can't seem to find any cases of women falling pregnant while on it. Do you know anybody who has? I'm just curious before I take a pregnancy test. My last period was 3 weeks ago and it was a pretty heavy one.
