Hello, I am 29 years old and recently found out that I have 3 fibroids, the biggest being 5cm. As a result my periods are very heavy on the second and third days so my doctor prescribed lysteda. I only take them on my heaviest days because my insurance doesn't cover any of the cost. I was happy with the results I was getting but ever since starting my periods have been so irregular. The last one was about 6 weeks apart and now this one hasn't came since the end of June. I read the reviews on this medication and it seems this happens to a lot of people. My question is should I be worried? Any advice you have would help. Thanks very much!
