Hi everyone I'm kinda new on here and I have a little situation I'm not sure about.

I had the IUD and never had periods and it was taken out on April 24, 2008 and then on April 26th I started bleeding with some small clots (Sorry if TMI) it last until the 27th and then nothing at all Was that my first period after the IUD? I started taking OPK test on May 7th and I have not had any + at all. I really don't know if I'm a 28 day or not I was always a 25 to 28 day cycle but I'm really not sure now. Do I count the two days I bled as my first period? and how long should my body take to get regular again? TIA Sorry if this don't make sense.
