Hello cherylks and welcome
It certainly is common to get strange spotting and bleeds through peri menopause. ARe you getting other symptoms e.g. flushes etc? I understand your reluctance to go to the doctor, (i hate having to see anyone in the medical profession) however, I think it would be wise to get this bleeding/spotting checked out to, at least, rule out any problems.
It's great to keep fit but I don't think extra jogging is going to help!!!!
It's a good idea to get a check up when you are in peri - if only to get a routine cervical smear and a review of the situation. Perhaps go to a meno clinic if you have one in your area? DG x
