Totally! I have the exact same symptoms when I am on my period too. My periods are all over the place so I can't keep up with them, then sometimes I panic like I'm having a really bad flare up but then a few days later my period starts and it all makes sense. I usually start rushing to the toilet throughout the day, my toilet trips are worse than usual, and my belly starts cramping so badly that I have to sit down. I also become exhausted, I will just be sitting there one day and this wave of tiredness takes over and I just can't function. So yeah like I say, a few days later, I come on my period- the tiredness disappears however the bad toilet trips stay and so do the terrible cramps until it's over.....oh, and don't forget the pregnant belly look that goes with it! I find hot baths with Epsom salts and hot water bottles help along with mint tea. I hope you feel better soon xxxxxxxx
