"i get migraines with aura so i cannot be on the pill. i got the paraguard (nonhormonal) june 2015. my body could not adjust. i would get my period at random times, very irregular, sometimes lasting 14 days. the periods were very heavy and clotty. i would fill a super tampon every hour. back pain, breast pain, and shooting leg pain down to my foot. it took 7 months for my body to adhere to a regular cycle with no spotting; however, the pain and heaviness remained. i put up with it for 1 year and 3 months. with preventing pregnancy- works like a charm, but side effects were too painful for me. finally i had enough. i got it removed and just got the nexplanon (progesterone only) inserted into my arm. wish me luck"
