I had an extended period from 8/17-8/25. pregnant now. would i have conceived in august or september ? due 5/28/13. original dd-6/2/13.

Cycle length: It depends on your cycle length. If your menstrual cycle is every 28 days, you may have conceived in late aug. If your cycle is 35 days you may have conceived in early sept. Dds are approximate, not an exact science. There is only five days difference between the origin dd and the revised dd. The truth of the matter is, your baby is going to be born when she/he is ready to be born.
