birth control
"Severe constipation started within 2 days after I started this pill (had been on low ovral for years prior, but currently unavailable),  acne followed, and now 5lb weight gain in past 3 weeks.   The stomach craps are so painful (constipation-related) that I am completely distracted throughout the day,  every day now.  I cannot wait to finish cycle and move on to another pill.  I've taken many different types of pills in the past 20 years...never had a single issue of any sort until this one."
