I just got on NuvaRing from Yaz 3 weeks ago.Since then, my breasts have been super sore and I'm tired all the time (also started a new job and am working 60 hours a week). I have a slight pain in my lower right abdomen, could that be from the NuvaRing and Yaz? It comes and goes throughout the day and has been for awhile. I know I am not pregnant, as there is no way I could be and I would've known by now anyway if I was.
