I am on day 28 of a 31 day cycle. For the last 3 days I have been getting quite sore cramps in my tummy on and off but no AF yet (obviously as its not due till wed!). I was wondering if some people get cramps up to a week before AF or not? I dont usually but I feel very PMT ish too so dont think I am pg, just wondered what to think of it? Could I have something wrong?
