Delayed period symptoms and conditions

I just wanted to add my experience for everyone looking just like me. I started using the Nuva Ring after having a scare with the pill in November. For a while I felt pretty good but I think thing are getting progressively worse. I've had extremely intense headaches at least once a month that are completely debilitating. I have also started having intense emotional swings every month since i've been on the pill. I just changed jobs recently and thought that a lot of my moods were due to that but now I'm realizing that the mood swings start 1-1 1/2 weeks before my period is supposed to start, lasting until my period is done. During the rest of the month I feel relatively normal. The mood swings include everything from spur of the moment crying, to anxiousness, to anger, apathy etc. I've been thinking that the ring was why but I really hadn't been sure until I started reading other people's experiences. I did experience itching although not every month, and more during the 1st week of having it in. I did not experience breakthrough bleeding. Also, I have experienced a delayed period every month, (taking it out Sun. and not bleeding till Thurs.). I would appreciate any feedback from anyone on here with opinions or experiences. Thanks!
