Wonderful! Isn't funny how things work out! I had endometriosis with PCOS and had the opposite problem..how do you bleed 72 days straight and not die??? LOL(oh well I sure felt like I was anyway I digress) but always without fail, I had diarrhea right before my cycles, so I understand! You will get used to your body telling you when it will start to cycle. I have to say though while I am very happy you are happy to be experiencing this, I am more happy I got mine all taken out! I love it when a doctor ask me when was your last menstrual period, and I proudly say February 28th, 2010! I get confused looks..then get ask how was the hysterectomy.....lol. Oh and as Aliemm said, you can try Midol for pain, I always preferred Alleve..back in the day, that wasn't an OTC med, and I had to get a prescription for it..So that should give you a clue to my age!! Alleve always worked better for me for cramps. You try different meds and see which one works for you, and a good heating pad will be your BFF! Good luck!
