NuvaRing and april 1

I've been on NuvaRing since April 1 after having my IUD-Mirena removed. I have been bleeding since, and it has been dark thick blood not like my period. My doctor was surprised to hear that I was bleeding at all since the IUD came out and NR went right in, the hormones never stopped. I have been so moody, irritable,and lost my sex drive, too. I had a bad painful break out (chest, neck, face, back) in the 1st month, it has since calmed down but left some scars. I also had terrible leg cramps in the 1st month, they did a scan and found no sign of clots in my leg. Just last week I had a terrible sharp pain in my chest which was tender to the touch and remained for a few days but eased away... now wondering if that was related? I thought I would give it time to straighten out (I am 29 yrs old and have yet to find BC that doesn't screw me up) and see if I can live with it. I may try 1 more month but I don't think its the BC for me, either. Thanks for all the info!
