I have been searching this all morning, for the last couple of months I have been having dull pains in my lower left abdominal, I read it could be ovulation but I can not tell because I do not follow a basic cycle,, some times its three weeks, and other times it could be up to five weeks until I have my period. Therefore, without having a regular cycle could it still be ovulation? I must admit I am a bit worried because I am sexually active and the last time I would of had unprotected sex would have been the day before the pain, I have been having pain for three days now this month but at the same time I thought my period would start this week if I followed myself on a 30 day cycle, and that is my main concern right now: if that dull pain means ovulation and having so sex before it, is there a risk, or since I am not in a regular cycle I could start my period any day this week?
