I had my mirena IUD taken out on Sept. 21, 2010. My period started on Sept.23,2010, lasted 5 days then got another period 10 days later on Oct. 13,2010(it lasted 5 days but very light) I took a pregnancy test on Nov. 7, 2010 and I am pregnant. Would you say the Sept. 23rd period was my last period or go with the one 10 days later on Oct. 13? I go to dr. Dec. 1 but am wanting to know how far I am.Thanks

I would say go with the 2nd date but I'm no expert! However, when you do go to the doctor I would tell him/her all this information as he/she will know which date to go by in order to tell you how far you've gone and when your expected due date (EDD) is likely to be.
