This didn’t happen to me, intact I was the opposite and took ages to come on! Was really late. I think surgery causes havoc with your body so I think it can go either way! Why don’t u go on the pill to regulate it, couldn’t be arsed with coming on as regular as that! Such an inconvenience!! I hate it once a month as it is!! Sometimes I just go straight thru on pills coz I don’t want it lol. Not good xxx
