I take birth control pills so that I have a period every three months (and always use condoms, too). This Wednesday I came off my pills to have my period. Normally my period will start 2ish days after I stop taking the pills, so I figured it'd start Friday. Thursday evening I even had cramps like I usually do the day before it begins. However, Friday I came down with a fever (starting to get better today), and now it's Sunday and I still haven't started my period. I'm worried why it hasn't come yet, since it usually only takes a few days after I stop taking my pills, so I'm wondering if being sick could have any affect on someone's cycle. Any insight would be really appreciated!
