Mirena or the pill

Hello ladies ! I am due to get my 3rd Mirena this Friday. For the last few months I've been conflicted on wether or not to go ahead and get another Mirena or try a pill. I really like the Mirena and have never had any problems with either of them. I have never tried a pill before, due to all the side effects and my family history of high BP, blood clots, heart disease and so on. The only birth control i have ever tried is the Mirena. I have talked with my doctor about switching to the pill and she really didn't give me any other options other than why change something when I've done so well on the Mirena, but obviously it is my choice. So, my question to all of you is should I try and find a pill that MAY work or just continue with something that has done so well for me the last 10 years?
