Okay I see this was posted a couple of months ago. If you are still experienceing weird periods, go back to the doctor and ask about being put on progeston (might have misspelled that). Its supposed to regulate your cycle so you can plan ahead. I am having a similar problem for a different reason and the doctor has said he will probably be putting me on that once he is certain of what is causing my cycle. My cycle in feb was twenty five days. Talk about a bummer!!!

To keep track, supposed to be twenty eight days from the first day of your period to figure out your next one. But when your cycle is crazy, I think all bets are off.

Thanks for the response. You are correct when saying all bets are off when it comes to the calculation once the cycle goes haywire. I did actually get another period -7 weeks later! Only lasted 4 days and haven't had anything since. I have given up stressing about it because it won't change anything. Hopefully the doc is correct and I may be completely finished soon!
