Hello, I found some inexplicable bruising on my lower abdomen (rather large and purple) and some on my upper thigh. I am on Nuvaring and also Zoloft, both of which I know have clotting and easy bruising side effects, respectively. I also smoke, though less of late than before a couple months ago. I am also taking Metformin and Trazodone. Just want to be clear that it s not something more serious than bruises. Thank you for your help.
