I'm also having sleep issues lately, for years I've had a strange insomnia 4-5 days before my period
starts, I just accepted that as normal for me. But this months cycle
was worse, plus for about 5-6 days I was waking up after only 5-6 hours of sleep, and being jittery and unable to go back to sleep, the day my period started I woke up and my heart was racing, lasted for about 5 minutes or so. And if I force myself to stay up I am very fatigued that day.
