im 44 and have irregular periods. recently I had 2 periods within 1 month and this month im over 10 days late. I have had on and off lower stomach pains for the last 2wks. mainly under my belly button and sometimes all accross or dull ache to the right hand side and also sometimes the left. Do I need to visit a doctor or is this down to my age?? :-S :-D thank you
