Ive been on nuva ring for years now and recently for the first time Sun dec 22 the condom broke while having sex. I freaked out and took plan b within an hour of the accident. I kept my nuva ring in and on scheduel and took it out tues Dec 24th like normal. I useally get my period late thurs night or early friday morning. If it doesnt come on time should i worry? and if i dont get it or it is delayed should i place my new nuva ring in on time like always?
