Im a 25 year old female with problems of the digestive and reproductive tract for the past 4 months. For some reason I get two periods a month. The first one and the second on ovulation day and its the third month its going on. I chart my temperature every morning for the next month and I see my GYN in a month to see if I'm even ovulationing and take it from there. I'm not on any birth control pills pregnant. I was just wondering what this could be causing this. It's the first time ever had an irregular mentrual cycle. The second thing going on is I guess it's IBS with constipation is the diagnosis the docotors gave it becaause so far they can't find out whats wrong. I've had every test done under the sun. Colonoscopy, CT scan abdomen, blood work but its all normal. My body is unable to have a bowel movement with a laxative Senekot or milk of magnesium. I have a good diet. No matter how much fiber I eat what I have is a motility problem. It's not fun dealing with all the bloating, pain, ect.. I'm getting a ultrasound or anal manotry done. Anyone have any idea what these two problems can be.
