Hello I am 24 years old. My husband and I have been trying to conceive a baby for 3 years. I've had irregular periods all my life. I found out that I have PCOS. My Dr. Prescribed me provera for 10 days 10 mg. (no period). The 2nd round I took provera again for 10 days 10 mg. 3 days after I completed the second round of provera I had a very very light bleeding that only lasted 1 day. Can someone help with my concern in why I only had a period for 1 day and how soon should I take a pregnancy test, Or is there any other worries I need to be concerned about. I got back to the Dr. the 2nd week of July. I have been having cramping steady headaches and throwing up or very nausea after my meals. I took a test and it showed negative how long should I wait before taking another test
