Can Clomid (clomiphene) cause pregnancy like symptoms about 7-10 days after finishing it? I'm on day 17 of my cycle. Very tired, heachache, cramps, nauseous, dizzy

Yes. Sometimes it can cause cysts or multiple eggs to grow and lead to cramping. It can also cause headaches and other vague symptoms. Once in a while dots in front of your eyes. Most women don't have those symptoms. They are not known to be dangerous in any way.
