DPO 11

Today, no spotting, yet. All clear. freaking out. head hurts, very strong smell to the urine. peeing alot. I can't even do a symptom roll call because I'm so freaked out. No cramping, vague nausea. Is it even possible to start your period earlier than 14 days past ovulation? I was under the impression you couldn't. Maybe I am ignorant about his too.
