when my period was 11 days away, i started to get a painful, bloated stomach on the night. it felt tight and uncomfortable. along with this, i was passing a lot of gas and having frequent trips to the toilet. the pain started to ease over the next few days but over the past week, i have still felt bloated and now i can feel slight cramping. i am due on my period in 2 days. i have read online that these are symptoms of pms. is it normal to feel pain so early on?
