Birth control problems

I have had Mirena since May so only a few months but... i have gotten cyst more than usual. I have been on my period none stop and if it ever does stop and I try to have a little sexual time with my boyfriend I bleed in the middle of sexual time. I no longer feel normal, i use be active and ever since mirena has been in i have been feeling less active. If i get it removed what is the best birth control that you have taken. I forget pills easily. And I got tired of having a break out if boyfriend wore condoms. Is there a birth control that you have taken and stopped letting your boyfriends use condoms and have yet gotten pregnant. Please let me know what you ladies?
