Cycle,herbex and strange discharge

Last febraury I had my period 7-10 th feb. I didn't track my March one, And I'm thinking I should probably have it during this week. I'm not sure if 10 days are over, It would probably be because of HERBEX and my medication that causes me to feel faint, and also I have a darker discharge than usual... I haven't gotten my period this month yet... Last month-- I couldn't remember if I hada period during March... I've been eating 'n kilo of chocolate for the past 4 days... I was 80 kilos, now it says I'm 85 kilos. I also had a sore lower back when lying on my stomach. And also Yesterday I was sitting and writing on skype. My rib on the right side was sore at one spot. My knee and hip was sore today. And now when I press my stomach below my bellybutton, I have a hard sore place below my bellybutton.... O_O Any clue?I am discharging light very very light brown and nomatter what panty some is yellow. I am wondering I've been marking down 4 days now, I should have had my period. I am marking down days until 35 days. If there is up until 35 days, I would have missed 11-20 days.... =0 Could Herbex weightloss change your cycle drastically? Please reply. My mother won't tell me what she was talking to the doctor about. Something to do with a virus of the brain or throat. I wasn't sure because she honestly never tells me or believes me when I tell her that I've been having back or stomach aches. I hate ti when she hides things from me.a long time ago I had dicoloring on my stomach, I removed it with sugar and creme mixture. Also I keep having aweful stretch marks. I am constantly constipated. Also your cervix drops if your close to period? Strange.... Can anyone explain what the longest time to skip cycle is. So far I know its only 10 days....
