"yes it definitely worked as a birth control but completely changed my personality in the meantime. the 14 day periods, tender breasts and stabbing pains, i could have coped with until it settled; but the anger out of nowhere, falling out with family and my partner, irrational crying, feeling totally emotionally unbalanced and actually hating who i&#039;d become were horrific. i&#039;d be very careful when choosing this contraception and look out for these signs and get it removed asap."
