my period is like clockwork every month. i'm on bc pills, and that's the only protection my boyfriend and i use. even last month my period was on time. well...it's been a week since my period due date and still nothing. i've got awful cramps, sore boobs, bad headaches, i'm having really runny, watery discharge, and i feel really nauseous all the time. i even had dry heaves yesterday for a minute. my skin feels really really hot and i can't get it to stop. my emotions are fluctuating wildly and my face has been breaking out. it's just nuts. i've been taking my pills right on time and i'm due to start my newest pack tomorrow. i've taken one test so far and it was a definite negative, but i'm starting to get more and more worried so I went about an hour ago to the local pharmacy and picked up a 2-pack of hpt's. if I don't get anything by tomorrow morning, I'll test again and see what happens, but I'm really worried because ever since my period first started (when I was 11 years old), it's been on the same day of every month without fail. I've never skipped a period before.
