Loestrin 24 Fe and change doctors

I didn't have a good experience with it. I was taking it to get my period started because it suddenly stopped. And then I got a really strange discoloration on my thigh that came after my calf hurt. I have had an ultra sound done to test for blood clots and have found none. I have been to up to 4 different doctors. ALL have said they 'don't know what it is'. Besides that, some have said it's hormones. Others have said its a skin problem. One said it's circulation problems. My OBGYN didn't really say anything. When I stopped the medicine, I was able to have my own periods, but then at that same time I developed multi-nodular goiter. And then my periods stopped again. My OBGYN told me to start on the pills again but I am scared because I don't know what's going to happen and my OBGYN just told me to start it again like everything was okay. I'm thinking of going to a different OBGYN. I just wanted to share my experience..
