I had an IUD for 6 years, without AF. I had it removed May 6th. First AF on May 31st. Cycle lasted 23 days. 2nd AF came on June 23rd. Since I have only had one complete cycle, my current average cycle is 23 days. (Lord knows I dont remember what they were like 6 years ago) According to glow, with a 23 day cycle, I would have ovulated on the July 2nd (af on july 16). Time can only tell, fingers crossed.
