I have been currently taking Junel fe 1/20 for a year now and last month I forgot to refill so I ended up not taking it that whole month, well after I had my period I started it again and I did skip a pill but took it as soon as I remembered well I have passed week 4 and I didn't get a period this is the first time this has ever happened to me I have never missed a period even on the pill has this ever happened to anyone? Could it be because I didn't take it last month and just started it back up?
