I am 18 years old so I figure my period isn t completely regular yet.. I have been 4, 6, and even 8 days late before. I am now a week late and starting to panic. My boyfriend and I use a acondom EVERY time and he STILL pulls out EVERY time and we try not to do it when I think I m ovulating. I have had slight cramps on and off for a week, my breasts have not swollen at all nor have the been tender. The past two days I have had a thick, white discharge which I usually get before my period, but I also usually bloat and my breats swell and become tender. I have lower bacl pain (which I usually get before my period). My sleep schedule has completely changed: I went from waking up at 7 am and going to bed at midnight, and now I m going to sleep at 4 am and waking up between 1 and 3 pm. I m probably stressing out too much and making it more late... But who knows. Please help!
